DV Info Net - Need Help for HD VIDEO presentation

Hi to all.. this is my 1th here.

I'm working to interesting project. We must produce a videoclip of 15 min in which we introduce plans (in existence and to realize) in the area around Naples (IT).

The clip will include

- photo (high) resolution of the zone (therefore full of details, houses, vegetation)
- 3D rendering of famous architects
- animation 3D of the Vesuvio (I have already realized it VIDEO with 3DSmax in format 1920x1080 non compressed)
- aerial showreel in HD (we have already made a test flight with Pana GS-500, the trailer ;-) , and we are contacting one specialistic company for the HD camera..probably Panasonic, equipment and operator)
- this project will be projected during conference at october (so at moment i'm not interesting to disc (blu-ray/HDDDV)

Now... my doubts.
- I would want to use Premiere CS3 because it is what I use. The safety margins. they are always valid? I must always hold text inside of those safe area?
- For the assembly I will have problems with a Dell D830 Intel Core 2 DUO T7500 2.2Ghz, 2 Gb RAM,Quadro NVS 140M 512mb, HD 7200Rpm ?
- What is format of digital file that company will give me? For now he send me 600 tif and i have mounted in Premiere timeline.. but 4 Gigabyte for 24 seconds... aren't my CPU capable... :(
- I've tested Cineform ASPECT.. and noticed that converting 600 tif in CINEFORM HD give me great help, even if it's at 1440. Prospect it's the same? my CPU will work at 1920 with Cineform HD?
- What i must ask to company? A video converted or captured with CINEFORM?

Thanks for the answers.. and excuse me for bad english..
