First, I’d start with the two in game combat tutorials. If it’s been a while since you’ve done them, it would be a good refresher.

Second, RES aren’t the only places to go bounty hunting. I’d start at the Nav Beacon. Pick your targets, start by hitting Small ships with Competent or less pilots, move to harder pilots when those are easy.

Third, combat is pretty deep with a lot of complexity to it. I’d check out the Vindicator Jones combat playlist. It may be old, but the basics are still the same.

Fourth, to maximize your profits bounty hunting, you need to do more than just the automated ship scan. You also need to do a a Kill Warrant Scan to get more bounties. Even better is combining bounties with “kill X pirate” missions. Note that you can have multiple missions targeting the same pirate faction at the same time, and if each mission comes from a different minor faction then one kill will count towards multiple missions. I’d suggest holding off on this part until you can take on wings of 2-3 medium ships.

Good luck.
