Please grade my recent pick up

Just purchased PSB image T55 towers, Image C60 center, Image S50 for surrounds, Image B25 for Surround backs, and Paradigm PW2200 sub in great condition all for $850 on CL. Was this a good deal? I have a Pioneer VSX-1020k I purchased new almost 2 years ago running the show. Does anyone know how to tell what version the PW2200 is? I think it is the V2 but not 100%. Also what is the best way to wall mount the S50s, the bracket is missing? What is a good stand for the B25s? Primary use is HT. Need some ideas for what I should get next please.
