NERDTree is great for browsing your project and managing your files, but for opening files (when you know their names) you really can't beat the speed of Command-T/PeepOpen. They're in another league.
I don't know how people work without it.
It can, in fact, search pretty much anywhere in vim (from the docs):
- buffers
- files
- directories
- most recently used files
- files around most recently used files
- most recently used command-lines
- bookmarked files
- bookmarked directories
- tags
- files which are included in current tagfiles
- jump list
- change list
- buffer lines
- quickfix
- help
