Too much Swap is not a problem though i think. It’s a waste of space but not actually something that causes bad performance or anything. If your ram is over 1Gb then you probably only need a swap if you use hibernate/suspend/sleep modes rather than shutting down properly but it will need to be at least ram size in order for the contents of ram to be saved to this handy space on your hard-drive. A little more than ram size is good. Twice Ram size means that when you get more ram you probably wont need to mess around resizing partitions 
Good luck and have fun
