The /team fortress 2 contains some game files extracted from the GCF (safe to delete -- anything needed will just get reextracted) and also your configs and anything custom you've ever downloaded (maps, sounds, etc.). If you want to keep these then don't delete your team fortress 2 folder.
The downloads folder contains other players' sprays. Safe to delete.
