The Undernet is simply one network of IRC servers. There is a lot of software available for IRC, most either freeware or shareware. One very neat feature of Homer is it's ability to load an image of the person or persons you are chatting with, provided that you have images of these people. They usually provide access to IRC on Efnet. If you use the Mac, you're pretty much on your own as far as setup goes.
Lags are delays between servers communicating to each other.
Splits are often repaired in a short period of time, so there's no need to log off immediately. If you don't see everyone re-appearing after awhile, then you may want to try switching to a different server. Some servers will disconnect you if you've not typed anything for awhile.
