Pokemon FireRed team suggestions

Hey guys, brand new to Pokemon here. Have been insanely hooked to this game after trying to get into the franchise for decades but just couldn't. For the first several days of my time with FireRed I was avoiding the min-max headache but as my Pokedex grows I just can't help it. I'm still very new to all this and don't really know much. I know how STAB works but I still don't even know all the type weaknesses. I pretty much just go off of logic when fighting lol.

My current team: Charizard Dratini Gyarados Jolteon Kadabra Snorlax

If you guys have any suggestions on changes to my team composition let me know. I don't care to be super competitive or anything but it does feel VERY good to have at least one guy on the team capable of steamrolling the opposing trainer. I am aware of some of these Pokemon having better replacement options but I like these guys. Gyarados and Snorlax are cool af and I got Dratini from a crazy slots run so I would prefer not dropping them if possible. Kadabra I won't be evolving to Alakazam as I'm not trading.

The main thing that's stressing me out in this game is the TM/HM's. I've realized that I've got to be very careful with which Pokemon I give them to as they are often not repeatable. So to simplify things I thought I'd reach out to you guys to see what TM's I should give to who so I don't screw up here.

Appreciate all suggestions, and I'm glad to be part of the community. Thanks guys!
