I don't see power for your PJ on your last plan , whatever you do , don't forget that!
. I totally understand not being able to afford to hire an electrician , we're expensive as hell . You said each of your red markers was location for sconce and receptacle , what are the outlets for ? convenience plugs , or are they for power seats or something else that will always be plugged in ? Will this build be inspected or are you flying under the inspectors radar ? All of this will affect how you wire your setup . Load calculations for what you will be powering so you know what wire gauge and circuit breaker size you need , number of circuits you'll need , and code even calls for a certain number of receptacles , based on linear feet of wall . There could be additional local codes I don't know about. You are also required to have AFCI protection for everything in your house that is not protected by GFCI , which I can tell you from recent experience could be a problem at your rack. I just worked on a house that another contractor wired , had to bring it up to code , and the power conditioner they had kept tripping AFCI breakers. I don't know why as I'm a newbie with HT , but I tested the circuit completely , replaced the breaker with a known good one , and the only way I could get the circuit to operate without tripping the AFCI breaker was to remove the power conditioner.
I'm not trying to discourage you from doing it yourself , and I'll be happy to help with what I can so you can get your project finished , or shut up and get the hell out of the way , I don't want to step on any toes. Either way , best of luck and I'm looking forward to seeing your progress.
Edit : something to consider , you should be able to have an electrical contractor do the engineering for the project without doing the labor , then you would (hopefully) have everything safe and code compliant , it would be considerably cheaper than having them do the whole job.
