[TxMt] Textmate Junkie, Ruby and Rails noob

I have been using (and loving) textmate for years - mostly for html, php, and some text manipulation.

I have all kinds of bundles installed, and think I understand the issue of scope... maybe.. Like, when i'm editing a php file, I still have the scope set to html so that I still have all my commands, be it from zenhtml, mhtml, php, etc or the ones I cant live with out - shift-ctrrl-w (wrap selection in tag).

i'm now starting to work in ruby and rails - and I have 2 questions: 1. are the ruby and ruby on rails bundles redundant or should I have both? 2. The bigger question - when editing ruby files it does not appear that I have access to the commands i'm familiar with (see above)

thanks for any and all pointers
