help me get the best from my kit

[special_K]

Hi Guys, new here so would appriciate some guidance
I have a Sony VPL HS2, other kit is listed below. i am at present looking for an amp and speakers, was looking at gettng them for the small room to go with the new tv, for hd reasons. can u guys suggest how i could use the kit i have with the projector, for example would i be best keeping ps3 with the tv to appriciate the hd picture or can i get decent picture uing projector, the projector is in the bigger room so decent soound in there would be better.
also i have mounted my projector on the wall, wa initially high so almost room mounted, chose the wall as it was easier to drop cables behind the wall, but the image on the screen was 'bent' bigger at the bottom (i am sure there is a correct term for this) it was wider at the bottom than top, used both manual and auto keystone correcting and auto helped but still the image at the bottom was outside the black frame. i lowered it and still had the same problem, although a lot less, it seems to get the image consistant both top an bottom, the projector has to be about middle of the screen height, this not ideal as the kids can then reach....any thoughts?

thanks in advance
