Questions about Wheel, Shifter and Stands.

Hello, my name is Kriss and im new to Racing Sim.
Im on Xbox One, and im considering buying a Thrustmaster TX and a TH8A shifter, and put it on a Wheelstandpro.
Is this a good wheel and a good shifter to start with?
And i was also wondering how it works to shift higher than 7th gear on the TH8A? is it just not possible or what?
Which games should i get? I already have Forza Horizon 3 and Forza motorsport 7. And which should i get out of DiRT Rally or DiRT 4.
Is project cars a fun game for a noob?
Are there any companies selling a handbrake for xbox one? all i find is people doing DIY’s and buyingh off of ebay.

The questions are probably set up really badly but i really dont know much about This.

I assume that setting the shifter to work as a Sequential or using paddles would be best for an 8 speed (and up) transmission. You’d be getting into Heavy Duty truck gear boxes trying to simulate a 8 speed H pattern in Forza.
