It's good that your questioning this, it shows that you have the right attitude.
You'll definitely need a bigger net, I recommend a folding one, this one in particular:

I use it on both my boats to save space.
I wasn't aware you were fishing form a kayak, that'll bring some challenges, but plenty of people do it frequently and have developed methods to unhook fish easily.
One thing I'd do in that regard is debarb your hooks, and switch to single hooks wherever possible. There's lots of excuses for not doing this, not a single one of them good. Keep your line tight and you won't loose any more fish than you would if you leave the barbs alone, and de-hooking is orders of magnitude easier.
Three other things you need right away:
A good jaw spreader, and it needs to be a big one.
I'd recommend this one, particularly on a kayak. It locks open, and works much better than the spring type.

You're going to need a set of long pliers. I Keep a set of these in each boat:

Hook cutters. There will come a time when cutting the hook is your only option, for both your own safety, and for the musky. There's cheap ones, and there's good ones, and there's no overlap. I highly recommend these, by Knipex:

Chasing muskies - particularly in shallow rivers - is a blast, if you have the right mindset for it. Lots of hours per fish you see, even more for each one you catch....but the "fish of 10,000 casts" stuff is nonsense. Once you know what you're doing, you'll at least see fish almost every day you go out.
