So im in the middle of sheetrocking my room above my garage and im running the HDMI cable from the ceiling ( projector ) to the wall were reciever is. Do i need to run ( 2 ) hdmi cables or just one?

Best thing is to run a conduit so it doesn't matter. When I built my space I didn't so when the industry shifted from DVI to HDMI I had to cut a bunch of holes and I put in two HDMI, glad I did, I have since broken one. Be aware that in a couple of years the HDMI standard will likely change in response to 4K bandwidth and copy protection needs.

so if you can, run a conduit for the parts of the wall/ceiling you don't want to cut open.

I ran two HDMI to my projector location AND a 2.5" conduit. I've never needed more than the first HDMI, but it's good piece of mind to have the empty conduit.

If u have a video switch aka receiver you only need one. if not youll need a cable for each device you want to send video from.

I would say a Cat 6 and HDMI is better to run then two HDMI. But better then that is running conduit, then in the future you can run whatever you want.

Another vote for conduit. One school of thought is to install conduit, run your initial cables outside the conduit and leave the conduit empty for future cables. I say if you are going to install it, you might as well use it for your initial cables as well. I recently had an HDMI cable go bad and if it had been installed beside empty conduit, I would have had to abandon it in place. Since I bought it at Monoprice and they have a lifetime warranty on all cables, I was able to pull the bad cable out of the conduit, ship it off to them and get a free replacement. If it had been stuck in the wall, I would not have been able to get the free replacement.

I ran a 2" conduit with two HDMI cables. I have an old no-HDMI receiver so until I upgrade 2 cables should be plenty.

It was surprisingly easy to 'push' the cables through the conduit.. didn't need any special tools.. I plan to stay low-tech and just tape any new cables to existing and pull them out to replace when standards change.. and they will..

Good luck with your build.
