Well, depends on what you intend to install and what your usage is. For a home system with a full install you don't need a complicated partition scheme. Say 2-3 gigs for root and your 500 meg swap (could probably do less - I've got 512 to match my RAM but never use it) and the rest for /home. Or you could get more creative. The Slack book discusses some of that and there are many threads on the subject around LQ. There is no 'right' or 'wrong', as long as you don't run out of room.
Of course, that won't leave you much room for additional apps if you don't just stick them in your home directory. But if you do a selective install or don't intend to add a lot it should be good. A lot of people (including myself) have a separate /usr or /usr/local partition. (But then again, I put my /home directory in /usr/local and stuck the whole thing on a separate partition.)
