Is all the work worth rooting?
with the 2.2 update coming soon Im not sure whether I should...

As long as you don't remove vital apk's such as backup assistant, you won't brick your phone. You can't overclock yet anyway as there is no kernels out yet.
The best reason to root right now, as previously mentioned, is to use your X as a mifi aka free wifi tethering. People have reported increased memory from removing the bloatware, so that is worth noting as well.
Not sure if it's made a difference yet, but setting profiles in SetCPU to downclock the CPU while the screen is off, etc, may positively impact battery life as well.

)But if you want to just fork over a one time fee of 10 bucks you could just go get easy tether on the market, or PDAnet.
Sure root is nice for tethering but I never really understood why people bothered to root just for that, since you can do it without it...
and in the case of the Dx here where recovery is not an option it may not be worth the risk if you aren't really a tech kinda person.
[wired only gets me to my laptop, but wireless let's my iPod touch and other devices connect].+1 Gamble, excellent points! Especially the note about the battery life via underclocking (I wonder if the Battery Manager is doing this under the covers a bit for us already...?)

I noticed that the CPU does jump around if you load up SetCPU and just watch it. It goes from 300 - 1000 rather randomly.
