Sorry. Being a troll. Beginners should ask anything in here really. We are more than happy to help - really we are. :)
Ok. Here is my effort, since I had to open my big gob!

A "good" beginner's kit is dependent on your weight, and as mentioned above, the environment you're going to kite in. I personally do a lot of land kiting, so I would obviously go for a board with wheels and a smaller kite. Sorry... tee hee... uncalled for.
Ok...
Ahem... take two!
A "good" beginner's kit is dependent on your weight, and as mentioned above, the environment you're going to kite in. First and foremost (oh I wish I had $2 for saying this too!), get lessons. Get as many as you can afford to get comfortable enough with what kite surfing is all about. It's not just hooting around on the ocean. It's about safety. It's about equipment. And of course it's about you. What do YOU want from the sport and why?
Ok. You've had the lessons? Good. Now onto the gear.
If you weight like most grommets around the 60 to 75kg mark, a 10mt or even 12mt kite is more than enough. A suitable TT board around 140 or even 150cm size is a good beginner size. It will certainly get you moving. The rest is up to you. Of course you need a harness to start with, but not essential (believe it or not). Anyway... a good bucket seat type harness is great because they simply don't go up your waist and crack ya ribs!
Once you get going and get comfortable with it, you WILL want to change your gear and customise it to suit your style and needs. Most of us keep our original kit, but many sell them off and buy greater and better things.
In terms of a good beginner kite - stick with known brands - North, Cabrinha and Ozone. They rule! The others are just... meh.. shall we say... MEH!! MEH!! yeah.
Anyway... not a grommet? An old 40+ kook like me? Well then my fellow friend... let me show you what REAL kite surfing is all about.....
