Unless you plan on acing the first attempt each time you record, you'll want to learn how to record multiple takes during a session. This is especially important when you record other musicians. Typically 3 good takes are ideal so that you can use them for editing in case there are any mistakes.
If you don't find the drum beat you like in the drummer function, you can create your own MIDI drum beat.
Extending tracks, copying and pasting, cutting, fading, etc are all important parts for recording.
Another way of building songs is by starting with drum "loops." There are lots of drum loop packs you can choose from and they are super easy to use.
