You can get all of the achievements in the first playthrough, but it will help to play the 2nd playthrough to level up. I would highly suggest playing co-op as it will speed up the completion time of this game by a lot. Remember to use the money glitch below, and take good guns off of your friends using this method as well.
GLITCHED ACHIEVEMENTS
A few achievements have been said to be glitched. Made In Fyrestone, Made in New Haven, The Weapon-Kill Achievements and Pandora-Dog Millionaire. If you start a new game with a new character than you will be able to get these achievements again.
An easy way to make the game go a lot quicker is by doing this. When you receive missions you can do all of them in a certain area before turning in. Just cycle through them in the missions menu, and then this will save you a bunch of time going back and forth turning in all of the missions.

Playing with players higher than you.
Playing with more players.

Fighting higher leveled players.
Playing a second playthrough.
If your having problems leveling up, try joining people games who are beating a boss, then you'll get the exp for beating them, which is normally a ton.

My Brother is an Italian Plumber - 15 points
Kill an enemy by stomping on its head
* At the first area of the game find one of the skags and weaken it with a crappy weapon. Then jump on it a few times. I believe that every time you jump on it, it does about 3 damage. Just kill it and the achievements yours.

This race track is in the Dahl Headlands. See the video below. Credit goes to Shadow9392 for the video.

Get A Little Blood on the Tires - 20 points
Kill 25 enemies by ramming them with any vehicle
This is slightly glitched, see notes above if it has glitched for you. In the first area, just grab a car and drive around until you have killed 25 people. You should be able to do this in about 5-10 missions.
Rootinest, Tootinest, Shootinest - 10 points
Kill 5 Rakk in under 10 seconds
You will probably get this during your first playthrough. If your having troubles, then when you have better weapons go back to one of the first areas and try again.
Pandora-dog Millionaire - 50 points
Earn $1,000,000
There is a weapons glitch that will help you earn
First Way -
It works a lot like theResident Evil Rotten Egg Glitch.One person gives someone their gun, and then doesnt save and exits to the dashboard, signs out or turns off their Xbox.Then the other person picks it up and when the first person signs in, it they will still have the gun as well because they didn't save. This can help with money as well because you can get a lot of money for selling certain guns.
Easier Way -
1. Get a friend to invite you to their PRIVATE GAME (you dont want people stealing your stuff - you will see why later)
2. Then go to Firestone as there is a shop there. Then when outside the shop, drop all of your stuff, a bigger inventory means more money. Just drop it all in the same pile and then exit without saving.
3. However get your friend to stay in the game as the host. Then boot up the game again and get him to invite you and you will see that all of your belongings are still on the ground in the same place you left them and remain there for a long time (I think until you move to a different location). You can either then drop all your stuff again and do the glitch again, or sell all the stuff you are holding now and then pick it all up again from the pile. Just remember to save after you are done.
This achievement is also said to sometimes be glitched, see notes above.
Fence - 25 points
Sell 50 guns to a shop
Just sell all the guns you pick up to stores.
Can't We Get BEYOND Thunderdome? - 25 points
Win an arena match
This can be boosted. Just grab a friend and go into an arena on the map. Then set the rules and kill them.
Duel-icious - 15 points
Win a duel against another player
This is different from the above achievement. Whenever you are outside melee your co-op partner. Then have them melee you back. This will start a duel, and now you just kill them.
Duelinator - 35 points
Win a duel without taking damage
Do the above, but take no damage from the opposition.
Group LF Healer - 25 points
Rescue a groupmate from death in a co-op game
Just revive someone while playing co-op. Very easy.
There's No "I" In "Team" - 30 points

Self explanatory.
And They'll Tell Two Friends - 10 points
Play in a co-op game with either an employee of Gearbox or someone who has this achievement
This is a viral achievement and most people have it by now. Just join a few online games.
Weapon Aficionado - 20 points
Reach proficiency level 10 with any weapon type
Just use one type of gun a lot. You will probably get this while boosting kills for the “Ding! Expert” achievement.
Facemelter - 25 points
Kill 25 enemies with corrosive weapons
Either pick up a gun with this element, or use an artifact and get the kills with your special ability.

You can find them from dead enemies, or buy them from shops. These change your players stats.
Fully Loaded - 10 points
Rescue enough Claptraps to earn 42 inventory slots
Just kill 1 enemy with this persons skill. I would suggest joining someone else's game who is further in the game. Let them kill some people and you will level up like crazy. It will probably only time 5 mins for you to level up to level 5. Then in a solo game, start a new game. Then equip your skill point and kill 1 person will the skill.
