Welcome!
1st- dress warm with multiple layers. You may be burning up on the ice from all the sun, or you may be freezing in the bitter cold. Wool socks with good boots, thermal underwear, possibly some snow pants and a good coat are all recommended. You'll be able to have a lot of fun on the ice if you aren't worried about the cold.
2nd- if they have a cabin I'm pretty sure they'll have all the gear, but if you want to throw down some $$$ here's some things you'll want to spend it on. If you're going first class: a snowmobile pulling an ice shelter with a sled to hold all of your gear is nice. A tent heater for once you get set up. A fish flasher like a vexilar or marcum is going to really increase your hook up rates. And a gas powered auger to drill the holes with (I like 10"). But you can drop a pretty penny for all of those things and I still don't have most of them.
Must have's~ some kind of auger. Manpowered ones are fine, or gas makes it a lot nicer but they're noisy and heavy if you don't have a snowmobile or sled. I prefer a Nils hand auger. Some 5 gallon buckets to hold your gear and chairs to hold you. Some ice rods if you are in a tent, or plenty of people catch them on standard fishing rods. I don't use special ice fishing line. I mainly use some fresh 6 or so pound flourocarbon line. You'll want an ice scoop to keep the ice out of the hole. A simple hook placed below a sinker with a worm on it will catch fish.
Methods~ my go-to starting method is a small 1.5" tube jig in pearly white or pink with silver sparkle. Greens and chartreuse work well too. I tie the tube jig on the line about 15" below a swivel with a bullet weight just above that. I tip the jig with worm, minnow bits, waxies, or meal worms. Carp spit doesn't hurt either
. Drop it to the bottom (many hits are on the way down), reel it in a couple cranks and wait. I use a very small twitching jigging action most of the time and feel for those sensitive bites. If I get ANY small taps I do a quick hook set straight up. If I miss, I drop it back down and get ready for the fish to circle back.
Try not to walk around much as the fish can spook from the noises on the ice, get away from crowds, be patient...and Have Fun! Good luck.
