As many have said it here, all your Gears list is GREAT!
Keep your Logic or DP or get any other mentioned Steinberg DAW, Sonar, REAPER and any other DAw (simply because Midi is far more advanced then PTools) to use for scoring and if u wanna be compatible, get yourself a little Hd or Le or M-powered Ptools system and u will be laughing thats all!
I myself got m-powered Pro Tools simply for compatibility in case a client came to me (as it is happening to me now) ask me if i got protools because he did session of PTools 6.9, i told him: No problem at all, i'm your man , bring the project here. The rest, i do them all in Nuendo, scoring, arranging, mixing 5,1 whatever you want & rock solid as all other DAW. Simply a question of Taste.
Good luck
