Noobish Questions (updated frequently)

2) After getting my mount at 40, is there anything I should be saving up for other than skills and equipment?

A new, better mount! Get your 2006 model kodo now!

Seriously though, I've found that I spent a lot of money on enchants when I had just hit 60 (particularly when you factor in the libram enchants). It's worth while trying to hook-up with a friendly enchanter and looking at the materials you're going to need for them.

Also, do a bit of research before splashing out on new gear. A lot of the time a very similar piece of equipment can be had for free from questing or running instances.

3) How frequently should I be updating the dps on my weapons? Every 2 levels? Every 4?

As Skand said, when you start to notice that you're not killing this quickly enough. It sounds pretty ephemeral, but it's pretty obvious when you're grinding and things go from "woo!" to "boo".

4) Are there any addons that give a timer for the health/mana/energy regeneration pulses? For a rogue, I find that starting combat right before the energy regen is rather important, and I often find myself most effective bouncing from combat to combat counting out the energy pulses.

There are a bunch of mods that will give you an energy timer. Check out http://www.curse-gaming.com/mod.php under the rogue section. Bear in mind that the 1.10 patch broke a lot of mods and that it's worth while shopping around for one that's been updated. :) (I'm currently using EnergyWatch v2, which seems to work post patch. You can find it here: http://www.curse-gaming.com/mod.php?addid=2233)
