Honestly there is a ton of equipment out there on the market, best thing you can do is research and try to get more familiar with everything. There's a few questions you need to ask yourself to know which direction to go in.
1) How much time do you have to put into trapping?
2) Are you wanting to just tinker with it or really go after the fur?
3) Do you have access to enough land/water ways to meet your needs?
4) Do you have the garage space or an out building to dedicate for storage, trap prep, fur handling, etc.
5) How much are you willing to spend money wise?
These are just a few things to think about. Best thing you can do is get with TFHA and attend some of their trapper training camps and events, get to know some trappers and ask questions at these events. Find out when they are having a fur sale close to you and go see all the fur and the process, again.....pick some brains. Water trapping for mink, beaver, muskrat, otter, and coon will require different traps and equipment than land trapping for predators. Good way to get familiar with equipment is to send off for some catalogs and just look over them. There's a lot to learn and prepare for, but it is fun and very addictive. DVDs helped me more than anything before I knew any trappers, even the bad ones I learned something from. Matt Jones DVD "After the Catch" is a fantastic fur handling DVD, James Lord has some great DVDs and he traps in West Tn.
Just do your homework first so you spend your money wisely, you don't want a pile of equipment laying over in the corner not be used.
These are just a few thoughts, hope it helps.
