Default Speed Density Conversion
I plan on converting my tuning over to speed density using HP tuners and I was wondering if anyone had any suggestions.

Just fallow the tutorial. It will be WAY safe to start.. Take your time with the V.E.. I'm one of those "Smooth" ve kind of guys.. Are you running open or closed loop?

I don't quite understand the question. I am using the MAF sensor still so I am using open and closed loop.

I always here people talking about the VE tables when using SD tuning. What are you trying to accomplish when working with the VE tables?

You are trying to get the VE table to accurately model actual engine air volumes at all loads and RPM's. You have to. You won't have the MAF to do it anymore.

MAF has 0 to do with open or closed loop

You can read more about it & the modes your vehicle can enter here http://www.hptuners.com/forum/showthread.php?t=8994

Does anyone know of a 2-BAR MAP sensor that will fit in the stock location?

Start doing some reading, based on your question about the VE table you need to...

Disclaimer: I am by no means trying to be a dick, however I have been down the same road and the best thing you can do is read up on it on HPT's forum. I have been running 2bar OLSD for about 1.5 yr now and love it but you need to know what you are doing to do so.. The MAF will be gone so it wont be able to correct for your mistakes if you make one.
