Sugar Daddy Achievement
Once you have $10,000, go to the bar in Sanctuary and put it in Moxxi's tip jar to earn the Sugar Daddy achievement. If you then quit without saving and continue the old saved game you will still have the money you put in the tip jar and the achievement.
In Three Horns Valley, go to the hideout where you fight the Bad Maw boss. Kill him, and pick up the Eridium he drops. Then, enter the Bloodshot Stronghold, and choose the "Save and Quit" option. Continue the game, return to Three Horns Valley, and kill Bad Maw again to get more Eridium.
