If you have some experience in videography, I recommend you rent a TV camera or at the very least a Canon XL1S.
If you're more amateur, go with SONY VX2000/2100. You can't go wrong with this one - perfect video quality. It would compensate for poor lighting technique which is pretty much inevitable since you don't have enough XP under the belt.
The MOST important part is the relationship with the models though. You'll need to make them feel relaxed, sexy, and wanted.
I would get a make-up girl for the shoot too - this really relaxes most girls. Also, for the lesbain shoots, let the girls chit-chat for some time - the make-up room is PERFECT for that. If you gonna eat someone's pussy, it helps if you know her name.
Last, start with the photos first - it's much easier for you and the model than video. It's a kinda warmup
Here's a sample from a recent shoot:
