Personally, I would do:
md0 = 300MB (/boot)
md1 = 500MB (swap)
md2 = remainder (pv.00)
I would then create a single volume group on md2, create / and home, but I
would leave 20-30% of the VG empty so you can expand later. That would work
out to like 10GB /, and 50GB /home, and leave you 15 or so GB for expansion.
