I had both 50/1.8 and 50/1.4 at the same time for about 3 months. I found AF speed and AF accuracy to be the same (low light included). Only AF noise was different.
Happy shooting,

I have had both too... I found the 50 1.4 a much better performer regarding AF accuracy. YMMV

Why wouldn't you recommend the 50/1.8 to the OP?

For wedding photography I would suggest a fast standard zoom in combination with a flash first and foremost. Learning how to operate a flash properly under these circumstances is a must. A standard zoom is the most flexible option. To complement this, I would suggest one or two fast primes (as a future buy) that are either wider or longer than 50mm (on a 1.6x crop body).
The 450D only really shines when it has a good lens on it. It would seem the 17-55IS is THE BEST choice but it is so prohibitively expensive.
If a 2.8 max ap is needed then it has to be the Tmron otherwise I really like my Sigma 17-70 but it isn't as fast at the long end (but, of course, it's longer )

The Answer is almost always the same, Tamron 17-50 and sell the awful kit lens
The 18-55IS is definately not an awful lens. It is, in many ways, just like the Nifty Fifty. It's cheap and flimsy build, it barrels, vignettes and CAs considerably. But the IS works like a charm and it's razor sharp, outperforming some of the L glass. Price-performance-wise it's brilliant. Check the review at Photozone here.
The earlier non-IS versions of the 18-55 kitlens, yes, those were afwul.
Regarding the AF performance of the 50/1.8 in low light: Just set the Speedlite to fire the AF assist only. The little red beam goes a long way in nailing focus.

Whoa! I admiit I've only had two, a non-IS with my 350D kit and an IS version with my 450D, but they were (in my opinion) utterly, unusably awful and slow.
I honestly believe Canon do themselves no favours putting a fantastic sensor in the 450D and sticking such an awful kit lens on the front. Those new to Canon might think thats all the camera can do.
Maybe the ones I had weren't representative, but I would never, ever use one again

My take on it (on the single copy I had the chance to play around with.)
Lightweight plastic flimsy build. Including a plastic mount. So what?? It's lightweight, so it's not that the mount has to carry large forces. It vignettes quite a bit. I'm okay with that, I like the look, so I won't hold that against the lens. It can't take a polariser well because the front end rotates. Speaking of the front end ... that's also the manual focus ring. Yuckk!! But then again, I rarely MF, so again no big deal for me.
It has IS. Pretty effective IS too. It is different mechanism from the big L lenses and I found it isn't as predictable as the regular system, but I easily got 2 to 3 stops worth of shutter time improvement from it, across the whole focal range.
Anything else? Well, yes, it barrels considerably and there is some CA too. Both is easily taken care of in PP. Oh, and it's sharp. That doesn't quite do it justice. It's razor sharp. LPH numbers, especially center numbers, beat quite a lot of L glass.
So ... ok, it cuts quite a bit of corners. But you get all this for €90 to €100. To put this in perspective, the 50mm f/1.8 II is in the €80 to €90 range over here in the Netherlands. Right now you CAN NOT get anything better in Price-Performance ratio.
