You can backup all you Steam games into an installer to save redownloading them - I think the option in the men is "Backup Steam Games" off the top of my head.

With W7 it pretty much sets itself up - you don't need to do anything. If it is new, it probably already has the latest firmware too, so you should be TRIM enabled already.
