Some help for a noob

[Ashock]

I've just picked up WoW. Although I tried to stay away from pay/play, there's simply nothing else out there. At the moment I have the following questions:

1) I am playing a warrior naturally. I have read a bunch of guides and they all have certain build and talent points distribution schemes. I am puzzled however, as to one thing: They talk about talents like Improved Rend, Improved Battle shout, improved this and that and also there seems to be a finite number of talent points. Do those "Improved" talents have pre-reqs like plain Rend or plain Battle shout, and how many of those would I have to take before being allowed to get to the improved stage. I am right now at lvl 9 and have not gotten anything yet as I am afraid that if I take the plain versions, I will run out of points necessary for the future. Is this the case or can I take the plain versions without running out of talent points in the future? I have to say that without any of the skills I am finding this game a difficult grind so far, soloing and all at least for now...

2) Edit: Just found answer, heh.

Any info about this and other simple noob stuff would be appreciated as I have not been able to find anything pertaining to the basics, well aside from the real basics on Blizz's site.

ps. So far I am not very impressed, but I still have another almost month to make up my mind, I guess.
