I've decided to go with the 30D vs the XTi for various reasons but I'm sure you guys don't need to hear about it. Anyways, here's my next dilemna--many threads are bashing the 'Kit Lens' but Costco, yes, I'm thinking of getting my 30D at Costco (again, for various reasons--cash back on my credit card, their killer return policy, etc) doesn't sell the body only and here's what they're offering:
1) $1,229.99 After Rebates
Canon 30D with 18-55mm EF-S & 75-300mm EF
OR
2) $1,149.99 After Rebate
Canon 30D with the 18-55mm EF-S Lens
Now, is it worth getting the 75-300mm for another $80 or should I go with choice #2 and just shop around for a better lens somewhere else? What's a good, all-round walk around lens that could almost do it all? I've been using my cousin's 28-135mm IS lens and it does a fine job for the most part.
I shoot everything from portraits, landscape, architecture, abstract, etc. I'm mainly a hobbyist looking to step up from the XT BUT I also shoot occasional weddings and portraits (for money). I need to stay within a budget though or else the wife will kill me. If I had to have one or two lenses and stay under 2k (that includes the camera from Costco, which leaves about $800), what should I get? I know there's not a do-it-all lens but you can lead me to think that there is. 
Here's what I'm thinking that's in range, which I can get possibly two of the following if I combo them correctly:
EF-S 17-85mm f/4-5.6 IS
28-135mm IS (since I'm familiar with it)
70-200mm f/4L
85mm f/1.8
50mm f/1.4
50mm f/1.8
Dream lenses:
EFS 17-55mm f/2.8 IS
EF 24-105mm f/4L IS
What's the closest lens to the 17-55 f/2.8 IS that's within reason/price? 17-85? Tamron?
Thanks for all the help guys/gals!

Peace be upon you
