The amp shouldn't be an issue. Majority of listeners don't pull that much power when they're "rocking out" Music vs. Sine wave is nowhere near the same current draw. The difference can be as much as 30amps(music) vs. 80amps(sine wave). If it craps out on you...invest

2. I will want to ad a subwoofer and am considering a powered sub, can i just use a LOC at the rear speakers?
You can use a LOC. You can also grab an amp with line level inputs. I don't recommend either. Most people don't notice distortion in their subs until it surpasses 20%

3. If I add a powered sub what size, given the type of music, 10";12" will one be enough?
Subwoofer performance is not relative to size. It's relative to design. However, displacement is king when it comes to efficiency.

4. Is any one already tired of the new guy asking all these questions on his first post?
Thanks in advance.
That's why I have so many informative links found within my sig
