AC Power Suggestions

I am looking for strategies to power the home theater system listed below. The TV and speakers are in a family room with a media closet/rack directly behind the TV wall (basically a storage area). I started down this path because there are no usable outlets in the media closet (except a 220 volt Sump Pump outlet) so I figured I should call an electrician and have one put in. This opened up a huge can of worms about what type of AC receptacles I should use, should I have a dedicated circuit/line(s) run to the closet, should I use a power conditioner/surge protector/UPS, if so which ones, should the audio be on a different circuit than the video, should the amp go directly in the wall. This is a house built in 1999 with underground wiring in Rochester, MN. In the 30 plus years I have lived in Rochester I have never had or heard of any complaints about the power (brownouts, etc.) I have never had any appliance die from a lightning strike. The only thing I might add to this setup is a beefy high current amp to power the MMG-Fronts, at some point. As you can see, this is not a top-of-the-line system, but not bad for a system that leans heavily toward home theater. However, I do listen to music on this system and would like to get the most I can out of the Maggies for that purpose. I have a limited budget, and therefore am looking for the best “bang-for-buck” way to power the system. Would a Porter Port AC receptacle be a good match for this system? Are dedicated lines necessary and how many? Is surge protection necessary in my situation? Will power conditioning/voltage regulating /UPS produce any noticeable results? Should everything be on the same outlet/circuit or should audio be separated from video or form sources, etc? I have done a lot of forum reading and I just can’t make out what is going to be the best mix for me. Any suggestions?
