Question [Swapper] How should I setup Swapper?

I'm now very familier with changing my desired ROM for another but when I see the settings for Swapper in the thread I then get a little lost.

How should I setup Swapper? There are loads of settings!

Does the size of the SD card make a difference?

Does the fact I've used the format utility in RAv 1.2.1G recovery ROM make any difference?

Currently I'm testing JACxHEROski v1.7r2 32B.

Thanks for any help!
