Caffleck, that is a bit harsh..
I'd suggest you start with Saurus Warriors and skink skirmishers. They are never wrong and will always do their job. After you've played a few games and get a hang of the rules, you can look to expand your army. A Salamander is a usefull addition, as you will field him in nearly every battle.
The SCOR are good, but not our best option. Buying a box of them does give you the possibility of converting 1 or 2 of them into a Scar-Vet on cold one, and give you some cavalry to boot.
The stegadon is a beautifull centerpiece of any lizardmen army, but I'd wait with buying all the heavy stuff before you got a good grip on the game.
The slann is very powerfull, and is pretty much mandatory in any games above 2000 points. You could go without him and don't be in any trouble, but if you take him you're in a much better position to win the game.
