I am one of those idiots who bought a cheap off-brand tripod a year ago when I got back into photography. It failed on my first outing. I just ordered a Manfrotto 190CXPRO4 4-Section Pro Carbon Fiber Tripod. I already have a decent ball head. Please tell me I did not mess up again.
I hope to be able to us it with a D800+70-200 f2.8 potentially with TC.
Yea, you probably did but you asked after you ordered
The 190 series is a bit light for a 70-200, especially with a TC. The 055 series is the minimum I would recommend. The idea is to match leg diameter to the focal length.
Gitzo issues some guidance on this in their downloadable catalog. I find their numbers right on target. Very conservatively a TC would put you into a Series 3. Many do that, others do not. Depends on which side you want to err on, and the costs go up a bit for 32mm Series 3 size legs.

Are you able to return or exchange the 190? While it more than likely will not fail on you (in terms of falling apart), Neil is correct in that you would be better served with a tripod at least as sturdy as an 055. You are talking about a lot of pixel density with a D800 and a long lens, and it will not take much movement for your image to be seen as less than sharp at normal to large sizes. I have the older Bogen version of the 190, the 3000, and while its build quality is OK, I do not use it with my D300 and long lenses.
