I'm trying to figure out which would be the best possible solution for me..

I installed slackware 9.1 on my laptop and created two partitions. one for
swap and one for linux native. but now i'd like to create more and put
/usr and /home in a seperate partition. should i reinstall completely and
just backup most of my important stuff in /home to a zip disk.. or should
i get a program and resize my partitions i already have to make room for a
new one?
