Medievel Cue Splitter is bad, with format-breaking methods of splitting some formats at least, probably not much better for MP3.
Some things off the top of my head and a very quick search. This can split and join:

These can split and might be able to join too:

As for how to create a cuesheet, you can edit it manually in a text editor, using syntax that is described at various locations online, or you can use an application that lets you choose times and will write a cuesheet for you.
We have many past threads on all of these subject here, so again, searching would be a good idea.
