Ok, so the questions I get on a daily basis are a bit overwhelming, this is my attempt to answer the most commonly asked and hopefully save everyone some time.
Basics
A few basics: I am in North America. Anytime I list prices or say a Skylander is "exclusive" it applies only to the North American, and particularly the U.S. Market.
Also, a good source for general info and where to buy Skylanders in your country is the website:
http://www.skylanders.com/
About the Game
First off, Skylanders: Spyro's Universe is a game from Activision, developed by Toys for Bob, that is available on every major system.
Starter Kit
The "Starter Kit" is a box that includes: the game, the Portal of Power, a Master Sheet, and 3 Skylanders.
-The Wii, PS3, XBOX, and MAC/PC Starter Kits all feature Spyro, Gill Grunt, and Trigger Happy
-The 3DS Starter Kit features Dark Spyro (exclusive), Ignitor, and Stealth Elf
--Also note the story line is different for the 3DS Version. The others are the same.
Elements and Skylanders
There are 8 Elements. Each of the 8 Elements has 4 Skylanders. That means there is a rough total of 32 Skylanders to collect. That said, there are actually more, 37 to be exact when you include: Dark Spyro, Legendary Spyro, Legendary Bash, Legendary Chop Chop, and Legendary Trigger Happy. There are also collectible Skylanders in Silver, Gold, Translucent Blue, Crystal/Clear, and Glow-in-the-Dark (all of which you have a legitimate chance of finding...Toy Fair stuff is listed later on).
Each Skylander will come with a card, sticker sheet, and web code.
Elements
There are a total of 8 Elements, as mentioned...here they are:
-Air
-Earth
-Fire
-Life
-Magic
-Tech

Keep in mind, the Legendary Triple Pack Skylanders are not available as singles at this time either.

Skylanders by Wave
It is often asked, "What is a Wave?" or "What do you mean by Wave __?" Here is the answer. A "wave" simply refers to the staggered release order. In October, at the launch of the game, you had access to quite a few Skylanders, but not all. Later in the fall Wave 2 came out...You still couldn't get Lightning Rod (Wave 4)...Here is the complete breakdown for your convenience:
Wave 1 (20 Base Skylanders, Dark Spyro, and Legendary Triple Pack): Spyro, Gill Grunt, Trigger Happy, Dark Spyro, Ignitor, Stealth Elf, Voodood, Drobot, Booomer, Drill Sergeant, Eruptor, Flameslinger, Stump Smash, Bash, Prism Break, Terrafin, Chop Chop, Ghost Roaster, Sonic Boom, Whirlwind, Zap, Legendary Spyro, Legendary Bash, Legendary Chop Chop.
Wave 2: Wrecking Ball, Dino-Rang, Hex
Wave 3: Double Trouble, Cynder, Slam Bam
Wave 4: Lightning Rod, Zook, Sunburn
Wave 5: Camo, Warnado, Wham-Shell
