To answer a few general questions. Yes the RED Pro Primes are solid and a real bargain for the price. RED Rocket is an accelerator card to speed you through conversion of RED native footage to other formats as well as offer accelerated playback- it's a great upgrade for a finishing system. Most folks I know are cutting with FCP on a Mac, although Avid and Premiere also offer successful RED workflows.
Regarding a specific package- you're asking for something outside of the scope of a forum post. I'd suggest working with a consultant to really help you pick all the specific accessories you need and can afford within your budget. Or grab my book- gives you a bird's eye view of all of this stuff so you can focus on your needs.
Please contact me directly and I can help you with everything. The primes are unbelievable and Peter Majtan and I were lucky enough to do some pre release test shooting with them several months ago. You can reach me at firstname.lastname@example.org. Also Sean at RED is an awesome resource for information and he is email@example.com. Please feel free to contact me and we can help with all your questions.
