Cassette Lockring Tool
That chain whip of yours isn’t all that useful if it isn’t complimented by a cassette lockring tool. You can pick these up for as little as $5, and they’ll last forever.
To help prevent broken knuckles, don’t use a little adjustable wrench for pedal removal. Find a pedal wrench that offers good grip and lots of leverage. It’s also helpful to remember that your left pedal is reverse threaded.
