Yeah, if you're even remotely serious about film, the camera should be considerably less than 1/2 of your budget.
IMO, something like this would be a very good setup that'll stay with you through camera body upgrades.
Canon 550D - $700
3 prime lenses - $500 - $2000+, depending on which you get.
Personally I like Nikon's Manual Focus AIS primes, which you can get used for reasonably cheap:
20mm f/2.8 - $200ish
35mm f/2 - $150ish
50mm f/1.4 - $100ish
Cinevate Nikon to EOS adapter - $25
Total - $500ish
Zacuto Z-Finder - $300
Zoom H4n - $300
Rail system w/ shoulder mount - $500ish depending on brand
D|Focus - $200 with gears
Cinecity Matte box - $100
Tripod w/ decent fluid head - $400ish
Total - $3000ish.
So you swap out the 550D for a new body in 2 years, and keep the rest. It's less than 1/4 of the cost of your setup, and you can easily swap in a better DSLR if you decide you need better lowlight performance or whatever, or you can stick to entry level bodies just as well. Even if you decide to go to a dedicated video camera sometime down the road, you can still use all of the other components -- even the lenses with DOF adapters. edit - eh, the Z-Finder would be worthless on a video camera, so that'd be one $300 loss.
edit: the reason I like Nikon's AIS lenses is they're compatible with more body brands than Canon's lenses are, and they're cheaper as well -- albeit at the cost of autofocus, which doesn't work with video anyway. But Pentax, Minolta, Olympus, Zeiss, Contax, and Leica have all made excellent manual focus primes that can be found for cheap as well, so shop around -- just make sure that there's an adapter out there for mounting them to your Canon EOS body.
