A few things, but I'll start with the most important:
Looking at where you live, I'm guessing that you're talking about Illinois, southern, or possibly northern Wisconsin.
Water temps right now are too warm, generally, to focus on musky right now. Anything over about 75° and you're risking the fish...the bigger the fish, the higher the risk.
IMO, fishing for musky without a musky net is an exercise in frustration. Been there, done that, and it just doesn't end well, for you, or the fish. Please avoid dragging the fish to a bank.
You absolutely need three things:
Jaw spreaders (big ones, I recommend these: https://www.muskyfool.com/toolsaccessories/p/outtooljawspreader )
Something to cut hooks with. I use Knipex 8" bolt cutters. ( https://www.menards.com/main/tools/hand-tools/shears-snips-bolt-cutters/knipex-cobolt-reg-8-bolt-cutter-with-notch/7131200sba/p-1444437030809-c-1550852385007.htm?tid=2125411723933154996&ipos=16 ) Nothing else comes close, but there are cheaper options. Cheap ones from Harbor Freight will work, but you need them, period.
Loooooong needle nose pliers. 8" won't do it, unless you want your new nickname to be "Lefty". I use these: https://www.menards.com/main/tools/hand-tools/pliers-plier-sets/masterforce-reg-15-triple-joint-needle-nose-pliers/68103/p-1503642864338-c-9156.htm?tid=6135679925076076382&ipos=15 . This is a 54" musky a friend caught. Imagine trying to dig a burried hook out of that mouth with 8" long pliers...
I'll leave lures to others, other than to say I've caught more musky on 7" Smokin' Roosters, #5 Mepps, and 1 1/8" Doctor Spoons than on anything else. I also throw flies at them, but that's a whole 'nother subject.
You're not going to get spooled. Musky don't run, or fight particularly hard (though the first few minutes, and the eat, are gonna be a lot of thrashing around, and big one is going to test you.
There are videos for holding them, watch them until you are confident. anything more than 30 seconds out of the water, after a fight, is bad. If the water is warm, it'll kill the fish more often than not, even if it swims away.
80# braid is fine, but you absolutely need a leader. Use wire. I tie mine into my main line using tieable wire (AFW Surflon is good, but there are others) with an FG, or an Alberto knot. Much better than all the altenatives...smaller, lest complicated, and they hold great. I tie a swivel clip (I use Mustad Fastach) into the business end with a Perfection loop. I have more than one rod where this set up is well into its 2nd season, and fish for muskies and pike a lot...multiple days a week, usually.
You didn't talk about your rod other than calling it a "heavy frog rod" but medium heavy and up is fine...again, the fight, if your geared up right, isn't long, and if your line and leader are solid, they won't break. Do not, under any circumstances, "high stick" your rod. Keep your hands on the cork...a 20# musky will snap your rod like a match stick if you reach up and try to lever it in above the cork.
To refresh: Unless you're going north of me a long way (I live in NW WI) odds are good the water is too warm right now. Let it get below 75° or so. And get a net...it's worth it. I use a 40" x 44" Frabil folding net, and keep one in each boat. There's less expensive options, consider looking on Facebook Marketplace...I know of one that just sold for less than $100.
I hope that all helps.
Post here, or PM if you have more questions.
BTW: River muskies are the best. Lake muskies can be bigger, but river fish are stronger, and way less pressured.
You are, if you're wondering, starting out exactly the right way: asking a lot of questions, and the right questions.
