Will your /home partition fit into the 8Gb drive? df /home should give you a clue, but, if it's too large, consider tar with a compression option. (It might make a good backup, too.)
Anyhow, save the /home partition, install the new system, and restore the parts of /home that seem appropriate. (I don't use Evolution, so I can't be specific.)
You might also want to think about distributions that are more stable than Fedora with it's approximately "every six months" update schedule (F11 is due out 26 May) and policy that terminates support for distributions more than one release old. For example, Ubuntu offers "Long term Support" versions that they intend to support for at least two years after release. (Other distributions may offer similar support options, but I've not looked for LTS since I don't mind updating frequently. Being retired, I've got lots of free time and enjoy playing with my computers, and there's no real-world down-side to breaking one or two of my systems.)
