if u want to get rid of bloatware you have to first root the stock rom
use cf root acc to ur rom ie. jvr jvt jvu or whatever
use titanium backup from play store
u can then uninstall bloat ware
as for touchwiz as far as what I understand from what ur saying u want touchwiz features but don't want the touchwiz launcher ?
use titanium backup and uninstall the launcher application . I think its called tw home or something similar . DO IT AFTER INSTALLING A DIFFERENT HOME APP LIKE ADW ! .
press home key and set ur new launcher like adw as default .
as for rom faryaab's F1 roms are great .
to get rid of the background stuff use auto killer task manager from play store
