How to correctly do dedicated lines for an apt?

Gentlemen
I know these cleanpower/dedicated line threads have been discussed before. I'm been totally convinced of the importance of having dedicated lines. That's why I'm taking the plunge myself and having it done in my place. The only difference is that I live in an 667 unit 31 story hi-rise and can only go so far.( Can't change the ground,can't isolate the power from the pole transformer etc. etc.). Here's what I believe covers most everything. I want to be sure I've covered all the bases before I bring in an electrician to do the work
1) On concensus #10 solid wire is the best to use(cyroed or not)
2) Put in as many outlets as you can.You can never have too many.
3) My standard 100 amp box is all used up; so just run a sub breaker box from it.
4) Clean all the breakers and mains and apply something like SST for conductivity.
5) Use high quality duplex receptacles (cyroed or not).
6) THIS IS THE ONE I DON'T UNDERSTAND Put all the new dedicated lines on the SAME PHASE.
7)Put in some 30 amp breakers for your high current items.e.g. Power amps
8) Run an isolated ground from each outlet back to the box DON'T UNDERSTAND THIS EITHER
Well, that's what I know. Appreciate any other suggestions to do this right

Thanks for any and all input

Item 1) okay

Item 2) No, you want to limit the number of outlets. Too many outlets can create ground loop hums.

Item 3) The only problem is you will need either a 2-pole breaker space or subfeed lugs in the main 100 amp panel to feed a new subpanel.

Item 4 & 5) okay

Item 6) Every panel has two colums and x number of rows. You want to put all your breakers in alternate row side by side or above and below depending on the wiring diagram. Electrician's job; he'll know.

Item 7) NEVER NEVER NEVER use a circuit breaker rated over 20-amps for convenience outlet branch circuits. Illegal and dangerous. Convenience receptacles can only handle 15 or 20 amps max. The purpose of circuit breakers is protection - not performance. Your landlord and his lawyer may take a dim view of this.

Item 8) You will need receptacles that are isolated ground rated and wiring with black (hot), white (neutral) and green (ground) wires. The green wire attaches to the receptacle ground. Simply run the green wire back to the subpanel. Install a seperate ground bus for the wires to attach to. Electrician's job for sure. Not an issue with Romex - romex wiring has isolated grounding.
