Really all depends on how nitty and gritty you want to get. Seeing as you have two polishers I imagine you're quite a detail addict.
Personally, I simply strip wash the car, clay it, hand polish any areas I see need a touch of love, and then seal it with a sealant, and after the next wash I topcoat with Americana.
For the interior, I like to enjoy the new car smell for awhile before I touch anything, so I just wipe away light dirt with a damp cloth as needed. After awhile I'll do a light interior clean and dress it.
