For file finding, I use FuzzyFinder with a shortcut to the recursive search. So far that and ctags been good enough that I haven't wrestled with fuzzy file finder textmate. The Command-T plugin looks neat though.

    " vim-fuzzyfinder plugin
    map <Leader>t :FufFile<Enter>
    " start recursive search with a comma. see help for 'fuf-abbreviation'
    let g:fuf_abbrevMap = {
            \   "^," : [
            \     "**/",
            \   ],
            \ }
