Looks like a good standard routine there. As Dblock says you may want to consider snow foam and tar/road cack remover. I'd personally got for LP over LPL by hand so at least it will make polishing quicker, just dont expect any swirl removal or correction from it. With the wax, dont bother topping up every month, you wont need to. Mine lasts somewhere between 3-6 months depending on how many washes I give it and RM will keep the protection topped up. On the topic of RM, make sure you get tropical, its easier to work with.
I would say for the new car, whip the wheels off one by one and clean, de-tar, and seal them. Makes them faaaar easier to clean later on and stops the crap sticking. I did this on my Zed(s) and worked a treat. Didnt manage to do it on the Alfa which gives off the most amount of brake dust and really regret it now. Once spring comes around I'll have them off and cleaned up properly then sealed.
