Thanks for the PM... missed your response/question with all the TMAC TShirt stuff going on. Not sure what you are asking, how many accessories can you plug into an autocom or can you run the accessorie's power from the autocom? You can plug alot of stuff into an autocom if you get the superpro avi, but I am by no means the authority on the autocom products... I just don't use them. My whole setup is bluetooth for phone and Ipod Nano with a custom remote for tunes. My radar has a visual alert plugged into it, so I could care less if I can hear it or not. For 2 way, my buddy and I use bluetooth cell phones. Whatever you wire up, go ahead and put a relay on the powerlet if you are going to run accessories on it. I left my heated grips on one time and killed my battery (luckily it was at home.) You may want to post a new thread and find someone who knows more about Autocom than I. The accessories you have listed do not total up anywhere near the capacity of the VFR electrical system (unless you have some weird gear,) so you should be all good to run them off the bike power. Sorry I couldn't be more help
PS - you're welcome to swing by... I love to work on any bike! You might have a long ride to get here :P
