Yep, this seems to be a given. I would only upgrade the bars if you have problems with them. As for me, I replaced the grips on my Jamis immediately to Ergon grips and left the bars as they were.

As far as tubeless tires are concerned, what kind of riding would you be doing? Many of the advanced mountain bikers I know personally do run tubeless, but as a new mountain biker myself I don't see a need to go to that expense given the nature of the single-track that I currently ride. If I progress to the point where I am riding gnarlier terrain then I will go there.

Congratulations on your new purchase, and whether you decide to keep it or trade it as you've mentioned, have fun, and welcome to TE!
