Should be plenty good. You've got a very capable kit, now go out there and take photos. No need to even consider newer gear before you've figured out the limits of what your current setup can do...
I'd always go for the best lens possible because that affects the pictures and they'll be around long after the camera has been replaced a dozen or more times..
If you really are a beginner, then a P&S would be better as photography is about having an eye for a picture and then taking it: just pressing the button on a good P&S will achieve that (providing it's been turned on, the lens cap is off and you're facing the right way)..
So have a look at the Panasonics offerings, LX2's are OK but a bit tiny and the FZ50 is nice. Later on you can buy a dSLR built around what you now know you need. And you'll have the other camera as a P&S for those days when wheeling a trolley load of camera bodies and lenses is just too much. Nothing quite like a camera with a decent lens on it that you can just slip into your pocket....
As a newbie, I was advised to buy better lenses, so I purchased the XT/350D with a 17-40 and a 50/1.8 Mk II. Six months later I bought the 70-200. I use them for landscapes/travel, portraits, sports, etc..
I suggest getting the XTi and the 17-85 lens that you'd prefer, plus an EX 430 flash..
Just a thought...
My mistake, I thought you had already bought the kit..
Nonetheless, that is not a bad set to start with. For a true beginner, you may want to start with the much cheaper Rebel series - just as capable image-wise, just lacking a few ergonomic features..
As for lenses, the kit lens is not a bad beginner lens, although something like a Tamron 17-50 would still be affordable, while giving you much higher quality and ability to play with f2.8 aperture..
You can also try a 50 f1.8, the cheapest way to get a big f1.8 aperture...
Your selection is fine; the idea that you should buy a point and shoot instread is just plain nuts, and the kit lens 18-55 is good enough for a lot of very nice pictures..
So's the longer one, for the vast majority of shots you might wish to take..
I agree with the others. The 30D is not a beginner's camera unless you have a strong background in film photography. I suggest a camera from the Rebel series with a cheap lens until you learn what you are doing..
