I've never waxed my Corvette Standard 5, and I've had it for around nine or ten years. I want to get a form-fitted case, too. I've had a Rockbass gig bag since I bought the bass.
Just use Howard brand 'Feed-N-Wax' from any hardware store. Can't help you on the case, other than hitting all the 'wanted' sections on bass sites ie TB, bassgear.com, Harmony Central, and Craigslist.
You can go to any hardware store and get a stick of bee's wax and a micro-fiber towel to apply it with. It shouldn't be more than a couple dollars. As far as the case goes, that's one of the few things I don't like about Warrick in general is the fact that you pay a good price for them and they don't give you a hard case for it. I would love to pick up a solid case for mine.
Do you need to wax it? You only need to wax the natural finish Warwicks. If you have a coloured oil finish you do not need to wax it.
The neck probably needs waxing from time to time. I have this one: I wax its neck ocassionally, more now that I gig with it (I was using other basses but I keep going back to the Warwick) but i don't go crazy with it. The body I don't touch it. I only ever waxed the body on my natural finish Corvette, which I sold a while ago.
Yes, silly. I have bubinga wood. There's a small area of discoloration where I rest my thumb on the bass near the pick ups.
I use kiwi neutral shoe polish for some time. The warwick online shop was selling their beeswax for a ridiculous 12 euros, EFFF that!
I use that Kiwi neutral on the neck of my Dingwall AB per Sheldon Dingwall. Its cheap, easily available and had no 'bad' ingredients in it like silicone. Rub on, rub off, then buff. Don't do it the day of a gig, because if there's excess it will be a bit tacky for a day or so.
old cotton t shirt. rub on light coat. "I" then sprinkle a few drops of water on the bass and rub off with the same old cotton t shirt. she should have a nice lustre after that.
I just use a paper towel or two to rub it on and another clean one to rub it off...then a cotton cloth to buff it out. Also, you're not really going to use as much as you think. Unless your bass is so dry that it soaks it up, I'd put on a thin coat, take it off and buff then if it still looks dry do it again.
