Yep, 24 bit all the way. Read more if you want to, but you don't need to. Knowing why is not necessary, as long as you just do it in 24 bit you'll be fine!
Once in 24 bit, you can turn the gain RIGHT down. Hit your drums like crazy and see what the loudest peak is. Try to ensure this is less than -6dB. Or even lower is better. This just acts as a safety margin. It won't SOUND better, but it reduces the chance of you hitting a SUPER loud hit and resulting in clipping. Compression during tracking is usually not necessary, and usually only recommended for those who really know what they are doing. I have found with my set-up, even with the gain at a minimum, I can clip my microphones with a loud source. They don't have a pad switch. Compression could save you in a case like this, as long as it's right after the mic.
If you do have one or two overs (clips), you may be able to get away with the old copy/paste from another part of the drum track, depending on your situation. So if re-tracking is a big hassle or not possible, this may be a quick and easy solution. But it won't always work if you don't have an appropriate duplicate part.
