i have been looking wedding shots posted here today and the tog has shot's at up to iso 3200 and they look great
i have a canon 40d how far could i push it before i start to get noise on in-door shots

try it and see! note the noise adds up with time also so longer shutter speeds get noisy so dont all into the trap later of thinking you will be alright at xx iso all, but yeah get to know how the higher iso's look from you camera at your usual shutter speeds. remember it always looks better on the little screen. note also you can get away with more noise on the black and white shots IMO.
 
I can get clear barely noisy pictures at 1600 ISO. If you going to use flash then 3200 all the way.
 
If you are using high iso, try to leen towards over exposing, as it'll hide some noise in editing :)
 
I'm happy with 3200 on my 30D, not bad at all, and its hardly leading technology nowadays. :)

I find the best thing to do is to expose correctly, if you have the available light to over expose, then the best thing to do is to reduce the ISO until you are exposing correctly.

Very true, but then you may find your shutter speed drops too low... swings and roundabouts!

a little confusing maybe... I didn't mention reducing shutter speed, just meant that if you have enough light for the desired shutter and aperture settings, don't over expose, but reduce the ISO.

Indeed, but if you don't have the light for the desired shutter speed and aperture (which is the case!) then try to lean towards over exposing. Noise is worst in dark areas, so limiting these at capture will produce the nicer image once edited.
