OOH OOOH! This is my niche. I know more about Cameras that I do about anything audio related.

Average glass vs. superior glass can make all the difference between shots the pop and shots that disappoint. Canon's EF-S 15-85mm lens is a perfect example. It's range is ideal for a crop format walk around lens, and it's reasonably priced, but it just doesn't quite cut it. If you really want great shots, you need the 17-55 F2.8.
The EF 35mm f/1.4L and the EF 135 f/2L. That's ALL I have to say about portraits.

If you want to be able to shoot at f/1.4, look at the Sigma 50/1.4. It's pricey at $500, but is sharp wide open. Not cheap, but the Sigma is the 50 I'm buying when I finally add one to my kit.
Odd. I've purchased one copy of the 50 1.4 which is treating me very well. Perhaps you need your body to be calibrated? I did have a 50D a while back that needed a microadjustment to work with my lenses. I wouldn't mind picking up a siggy as well.

If you ever plan on upgrading to prosumer or even full-frame, I would recommend saving pennies for Canon glass and start with zooms. But definitely take baby steps and sell the kit stuff and grab the 50mm f/1.4. Welcome to the other expensive hobby
Remember that you'll sacrifice some IQ for the range with zooms. While there are people who are completely set on primes, zooms have their place and the 24-70L I use everyday is sharp enough for my purpose.

Primes are definitely a great way to get the best performance in terms of maximizing resolution and minimizing distortion for the money. You still want quality though, and the 50mm F1.8 really.. isn't that great, especially if you want to go wide open, as its resolution is kinda "meh" until you get into the F4 range. The 50mm F1.4 on the other hand is tack sharp at F2.8. That makes a big difference.
In this case, spend the money. The 1.4 is around $350, which is frankly pocket change for a high quality lens.
There's no other way to say it, the Sigma AF 20mm f/1.8 EX is just a piece of crap. Avoid. Canon's 20mm F2.8 is infinitely better, but depending on what kind of shots you're planning, you may be better served by replacing your 18-55mm kit lens with something like Canon's 17-55mm F2.8, which is a really nice lens, and using that at 20mm.
True and not true. L lenses are built for APS-C, APS-H and full frame sensors. The EF designation allows it to be used on all of the Canon mounts. The only limitation of currently in EOS is EF-S on APS-H and FF. A majority of users use L lenses on APS-H and FF, but you'd be surprised on how many xxD and dRebel users use L lenses.
I really hope you're joking about the quality of the 50 1.8 until f/4. I hope for your sake that you are. I've owned the nifty-fifty before, and it's a great lens for the value. Cheap and fast, and while there are discrepancies between copies, some are surprisingly sharp AT f/1.8. Stopped down, most copies are sharp at f/2-2.8. Also, the 50 1.4 that I currently own is sharp - open at f/1.4. This whole 'idea' you have of stopping lenses down is half-true. Lenses are sharp wide open, while there are bad copies.
The 35L, 135L, 17-40L, 24-70L, 70-200 f/2.8L, 50 1.4, 50 1.8, and 15 2.8 are lenses that I own or have owned in the past - and they're ALL sharp wide open.
The only lens that I can recall being soft open is the 16-35 2.8L, which is the worst lens L I have owned to date.
