Basically I'm trying to understand some of the terminology and basics that go into the electrical systems used, in order to decide which motor/esc/servo/batteries to buy.

Looks like you are off to a good start.

Objective: To have fun learning about RC, bashing around in the neighborhood, and practicing driving skill on the local outdoor track. My vehicle of choice is the new TLR 22T. I dont want RTR quality components, but I also don't want high end, as I am really just a beginner. Quality, mid range is the idea.

Good choice, as if the 22T is anything like the 22 buggy it should be fairly durable, good consideration for starting out. Only caveat is the ST class turnout is weak at some tracks if you think you might try racing at some point.

Motor: I have learned that sensored/brushless is where I want to start, with a 13.5 T or 17.5T. I'm pretty sure 540 is the size I need, but don't know if theres anything else I should be taking into consideration. The Team Epic D3 or Tekin Redline appear to be ok for me, unless I am mistaken...What about Novak Ballistic?

Yes, 540 size motor. Any of the 3 mentioned is a solid choice IMO. Perhaps stick with ‘stock’ 17.5 if you think you might try racing soon, otherwise a 13.5 is a nice compromise for a little extra fun power without being a handful to start with.

ESC: here is where I am more confused. I know I need a sensored brushless ESC to go with the motor but, I'm not sure which because some take different batteries (i.e. have different input voltages). The Tekin RS gets a lot of praise, but is it more than I need at my level? It seems to only take 3S Lipo, unless I am mistaken. What about the Novak GTB2 Sportsman...

Those are maximum voltage/cell ratings. Either will be just fine on 2S, what most run on this type of RC. And required for racing.

Batteries...Correct me if I'm wrong but, you only choose batteries AFTER youve chosen the ESC right? So I'm not sure if I should be aiming for 2S or 3S at the beginner level. Also, what about C rating. I saw some cheap 25C 7.4V Onyx Lipos, but is 25C enough? They are only 2S though, so unless Im missing something, they dont work with the Tekin RS ESC...

Yep. Recommend sticking with the standard 2S. 25C is certainly enough for starting out. Higher C in this situation will provide a little more punch, but it’s a small difference for most, especially just starting out.

Lastly, Servos. IO was just going to get the Spektrum 6020, to go with the Spektrum DX3C I was going to get. I know I dont need High Voltage or High Torque Servos at my stage, so is this one decent for the price ($49.99).

You don’t need high voltage, that’s mostly a Nitro thing. High torque is always good for a truck. The 6020 should be fine.

I think that covers it, any advice you can provide, or technical information you can help me with would be really appreciated!

No problem, and Welcome to the insanity!
