HI, need advice

[sharelove]

Hi, I am completely new to this and there is no one at this time with whom I can connect in person here in Nelson that has experience and time and can share knowledge :-(
The good side to the internet is I can connect with all you wonderful people from all over the world! Please feel free to post your thoughts to my newbie questions!
Firstly, I should tell you what I have and where i'm going with it: I have a 90gal or 339Liter glass tank. I've bought a FF (foam fractionator) a few powerheads, a jebo canister filter, a couple of very good beginner books and other paraphenalia. I introduced 70lbs/32kgs of live uncured rock from Tonga. I just put the rock in a week ago. I've got nothing else in there now. I will be adding sand and live sand, and then I would like to start adding FISH!! and a cleaner crew - hermit crabs, snails etc...
So what I would like to know is, at this point, I just took my first readings re: tests, and my results seem low to me. I should mention that I have done some water changes in order to get my salinity correct. For the first part of the week it was a bit low around .014 -.017 but now i've dialed it in at around .021-.022 (getting used to using the cheap plastic "deep six" hydrometer...)
Ammonia >0.2
Nitrite >0.1
Nitrate >10
Ph between 7.8 & 7.9

What do you all think? am I doing OK? Is my rock gonna die!!!???

:-)

thanks again for your patience and hearing me out. I look forward to participating as I get better at this!
cheers,
marc
