I like P21S, Meguiars or Zaino Z-7 for car soap and I highly recommend a sheepskin mitt ($5 WalMart, Eurow brand-pick the softest) and waffle weave microfiber towels for drying the car to prevent water spotting. For interior work, I recommend 303 Aerospace for the dash and plastic parts, doors, etc. I also recommend a weekly or biweekly vacuuming which works wonders.
As I had said... Optimum is clearly a second choice to a regular wash, but it is def. a good option for those of us who don't have easy access to a hose or who live in a cold winter climate.
I agree that Zaino Z7 is a great wash. It's what I use 75% of the time (I use Adams wash in a foam gun the rest of the time). In my experience P21s TAW is a bit too strong for an everyday wash and tends to strip off my LSP.
Picking up some MF towels (waffle weave) for drying is a great idea. If you really want to get crazy I have the CR Spotless and I was surprised at how good of a job it does.
For the interior I used 303 Aerospace for a number of years and really like it, but if you prefer something that leaves NO residue and a completely matte surface you can't beat Einzett Cockpit Premium.
