Balance
I noticed when I accelerate my car pulls to one side. So much so that it will even sometimes spin out. My LHS shop looked at it but couldn't figure it out. It doesn't seem to be the steering servo as it doesn't do it when I gradually accelerate.
Recently, I was holding my car and I noticed the front, right CVA bone was wobbling when I increased the throttle. So I replaced it with a new spare I had. The car still seems to pull but not as much. Could this be the issue or am I imagining it got better? Any thoughts as to what will cause this and how to fix it ?

You should first look at tweak, e.g if the chassis sits flat on a flat board.
Anything else could be useless if there is just tweak.
Then have a look at your diff

Let off/brake earlier entering turns. Smoother throttle exiting turns.
Someone told me "slower is faster". Sounds crazy until you try driving that way.
If all else fails, get a TC6.2. It's a much better designed car. Easier to drive.

Tire balancing
There are different balancers on the market, some specifically for car tires. I use a Du-bro prop balancer since I also fly rc planes. There is also sticky back balancing tape in rolls available at AMain Hobbies among other online shops.
I can't post the URL's for the equipment but go to AMain Hobbies and look up tire balancing. They list the Losi and Du-Bro balancers along with the balancing tape.
The process is simple, once your tires are mounted and glued, you place the tire on the balancing jig and the heavy side will rotate to the bottom. You then cut a piece of the balancing tape and stick it on the inside of the rim at the highest point. Experience will tell you how a big a piece to start with.
Depending on the imbalance, the tire will now rotate to the new heaviest point. In some cases, you will need to make a bigger or smaller trial weight and replace the original weight. If it rotates not quite all the way down, you might have to move the balancing weight one way or the other to find the exact placement.
The real key in balancing tires is to make sure you have the tire exactly centered on the balancing spindle to begin with. When you reach the point where you can spin the tire and it never stops in the same position, you are very close.
Take note when you are holding your car and revving the motor. Do the tires look like they are wobbling and the turnbuckles appear blurry because they are vibrating so hard? This can translate to loss of traction because of poor contact due to the vibration.
If you race VTA, balancing is a must as the HPI tires and rims are so big and heavy it makes a huge difference in the handling.

Just bought a TC6.1 WC for TC 17.5 class. What would be a good setup to start out with. I have a TC6 that I run for VTA but I'm not sure if that setup would do well in a different class. The track that I mainly run at is 73 x 40 carpet medium traction. Also what is a good brand of rubber and wheels to run? I've heard of sweeps but never ran them.

Thanks I'll start with my VTA setup then and go from there.

Honestly, I might check the balance once a month and usually they hold their balance but sometimes the clay might fall off if I get tangled up in lap traffic or take a nasty hit into a wall so it might be worth inspecting your clay at the very least and checking your balance periodically. I guess it's all about how anal you want to be about it.

Has anyone had the problem of the rear end fish tailing just slightly for the 1st couple of feet when starting at a complete stop?

Also try lowering your rear center of gravity.
Here's what I recently experimented with my TC6 on the rear links and I couldn't get my rear end kick out no matter how hard I hit the throttle in today's racing:
