In direct answer to your question, there's not a great way to step through the code. As far as I know, there isn't a way to load GHC into GHCi. Personally, I think a lot about the type-checker and so use -ddump-tc-trace a lot. You can line up the output with the code to see what is going on. Also, if you have a DEBUG build (devel1 or devel2 in build.mk), you can use pprTrace to print out from pure code.
But I surely second my colleagues in suggesting a small scope to start. My own start was in Template Haskell, which I found to be a great doorway in.
