If you are interested in video work/encoding it would be worth getting a Z68 board which will let you utilise the on chip graphics/sandybridge acceleration.
You could also use a cheaper H67 board but as you are getting a K chip I guess you want to overclock which you wont be able to do with that chipset.
As far as I can tell the main chipset differences are :
H67 = On chip graphics
P67 = Overclock with multiplier
Z68 = On chip graphics + overclock with multiplier
Re the SSD I have had one as a boot drive for a while now and not noticed any problems. I do struggle with only 60GB though. Even just using it as a boot drive for W7.
Wouldn't do without one now as the user experience is so much better in my opinion. It's just 'nice' that programs open instantly
