Wow! Are you sure you have enough space there ???
Seriously though however you set it up it's up too you. Personally I'm not an enthusiast per se, but having followed a slightly modified version of gentoos recommend, it's worked fine.
Their basic system is /boot, /swap and /, but I have maintained a seperate /home for a good while now - in the hope that I won't loose my customisations, data, address books, etc etc.
Looking at your post kuplo are you going too run 1 or 2 distros? because it's showing 2 /swap partitions between the 2 drives. If you're gonna run 2 distros then it's probably less hassle to have a common /swap and /boot. You can also have a common /home as it's only really the need for seperate / partitions so that each distro has it's only location.
Oh and when I installed SuSE 9.3 over the top of the mandriva 2005LE I did experience some problems with my /home - I never did find out why, but the SuSE seemed to want to do it's own thing (and yes, I might have got it wrong). It wouldn't let me into the original /home.
After a couple of weeks of meddling I just reverted to gentoo as I know I could make it work without much in the way of problems.
'Sup to you really but the above are the only things that made me think a little.
Good luck
