I'll also add one more tidbit-

Proper Filemanagment! The number of separate files you will end up dealing with can be overwhelming. Use the project feature of inventor. It can be a little restrictive at first (not being able to switch projects on the fly, for instance). The benefit is no unresolved links when you go to move that assembly to a new computer.

Pick a naming scheme for your files and stick to it. Don't be afraid to have long filenames either! The more descriptive they can be the easier it will be for you and your teammates to work. It's no fun opening 3 different files to find the right part just because all the names where 'part1.ipt, part2.ipt, part3.ipt' and you couldn't remember which one you worked on last night. The important thing is consistency.

I try to keep track of major changes with Rev Letters. If I feel a design has changed significantly, I'll start a new project and copy the files in there. This keeps the last revision intact in case I need to compare the two.
So Rev_A_Bearing_Pocket_plate.ipt might 2 weeks later be Rev_E_bearing_pocket_plate.ipt. I'll keep a .txt file with each rev that keeps track of major changes like a version history for a program. The easier you can make working on the project the more people can help and then quicker things get done.
