Changing user folder location?

I caved and bought an I7, 27" IMAC. This is my first ever Mac after 25+ years of Microsoft products. Yes that includes the good old days of DOS. I don't need to be reminded that the "new" one will be out next week. I needed the computer months ago, but now have a couple of jobs that required my attention, so waiting was no longer an option.

So my first question is, I did get the SSD and HD option and would like to keep the SSD for OS, VM's and files I am working on. Is there a way to remap the user folder location to the HD and not the SSD? I created a new IPhoto Library on the HD and dropped the Link into the Photo Directory, but it would be nice to make the default location be on the HD.

Next, I have used Quicken for years, and the MAC revision gets horrible reviews. Can anyone recommend a replacement for Quicken? Anyone using Quicken for MAC and find that it’s OK?

My last question for this post is memory upgrade options. I was looking on newegg and they have Corsair memory. Is anyone out there using Corsair memory in there IMac? Looks like everyone recommend Crucial or OWC but the Corsair 16GB (2x8GB) DDR3 1333 (PC3 10600) Memory for Apple is $94USD after rebate, so very tempting if I knew it would work.
