I've actually just started waxing my own skis.
I got middle-class ghetto stylee and use 2 dining room chairs with grocery store bags laid out on the hardwood floors to catch dripping wax.
I've been double waxing my skis for summer corn, laying down some purple all temp Purl rimmed with One Ball Jay all temp soybean (Purl dripped down the middle, OBJ dripped along the sides) as the first coat, then letting them bake in the backyard for a day, cool, then scrape. For the second coat I go with some Purl Yellow Spring and Orange Spring wax, again dripping the yellow down the sides and the orange down the middle. Bake again, then scrape. This has been working really well on the summer sun-cupped and corn snow I've been skiing in late May, June, and July.
Oh yeah, when not using the dining room chairs as my work bench, I usually use old plastic milk crates.
I'm trying to go as "green" as possible, which is why I'm working with the Purl and OBJ waxes, though I do have a few flouro waxes still lying around.
I just purchased a basic kit from Purl, which included a number of bars of their natural wax, a scraper, and a guide to basic patterning and waxing. http://purlracing.com/osc/catalog/product_info.php?cPath=13&products_id=30&osCsid=d0fd7f25019c9d565bbd9216dcff4048
some folks are pretty meticulous about scraping, wanting to get it perfect so you don't really see the wax. Me, I do about 3-5 scrapes, but don't worry about getting it super even as I'm not racing and more often than not skiing uneven, wonky terrain. That and a buddy of mine who used to instruct at Heavenly is fond of telling a story about a crazy Austrian that ran the ski school several years back who would just slop the wax on and go on his way w/o scraping. The wax is gonna wear off after 3 days anyway, so the more the merrier was his thought on the subject. But to each their own (me, I just get tired of scraping, so I do it like I said, about 3-5 times and then roll with it...I basically make sure any large clumps are smoothed out and even).
This local Tahoe shop that Sierra Jim used to work at, The Star Haus, has some basic articles on tuning and waxing that I found decent:
