Planning to buy a Canon Digital Rebel XT...

Planning to buy a Canon Digital Rebel XT as my first SLR and can't decide on the lenses. What I know is that my current camera (Sony F717) has a fixed lens that is equivalent to 24-125mm and I would like to have a lens set that is wider at both ends.
I am already decided to take a Canon 50mm f/1.8 II prime lens - for portraits and for low light situations (in-house sports, ...). All experts say that this is a must have lens - it is very fast and gives wonderfully crisp pictures for a price of 75-80$.
Now I can't decide whether to buy the kit lens (Canon EF-S 18-55mm f/3.5-5.6) or go and buy something better right in the beginning. After reading a comprehensive review of the best Canon lenses from Bob Atkins I am more confused then before.
One of the best compromise "walking" lenses is actually narrower then Sony's range - Canon EF 28-105/3.5-4.5 USM. Buying this lens would mean that after some time I will probably buy the kit lens or a 500-600$ lens for that wide end and a Canon EF 75-300/4-5.6 for the telephoto end. That is a total of 4 lenses - what a waste!
Now, if I would relax myself a bit on the money, I would take a Canon EF-S 17-85/3.5-5.6 USM and then extend to the telephoto end with Canon EF 75-300/4-5.6 or (new, much better, more expensive) Canon EF 70-300/4-5.6 IS USM.
Lets see what the numbers say:
Option 1 - kit lens + Canon EF 28-105/3.5-4.5 USM + Canon EF 75-300/4-5.6 = 100$ + 200$ + 150$ (or 450$ with IS and USM) = 450$
Option 2 - Canon EF-S 17-85/3.5-5.6 USM + Canon EF 75-300/4-5.6 = 520$ + 150$ (or 650$ for the great new Canon EF 70-300/4-5.6 IS USM) = 670$
My start-up lens choices vary from the recommended 350$ (kit + Canon EF 75-300/4-5.6 + 50mm prime) or 270$ (Canon EF 28-105/3.5-4.5 USM + 50mm prime) to 1250$ (Canon EF-S 17-85/3.5-5.6 USM, Canon EF 70-300/4-5.6 IS USM, 50 mm prime). We must also remember that I will also have to buy the camera itself (500-600$), a carrying bag (50$) and a CF card (100$). Ouch.
Spending 2k$ on a hobby, that is just very not me.
