Frank has already hit a couple of the things I was planning to mention. Usually it is best if you posted some examples of the images you've taken. The old adage that a picture is worth 1000 words is quite true for trying to analyse what issues you are having.
My guess is that the glare is likely caused by one of two issues. This is caused by internal reflections off the filter or lens elements. A lens hood may (or may not) help here, so if you have one for that lens, try it to see if that helps. The other possibility is that your lens filter is an uncoated one; these are particularly prone to flare. Try shooting these shots without it; if the flare goes away or is reduced, that is your problem.
It's really hard to give advice beyond that. A flash would not be an option in any case, as it would overpower any lights on the decorations. Frank has given you the same advice I would, try the tungsten white balance setting on your camera to see what that does. The auto white balance often gives strange results under tungsten lights.
The lack of sharpness could be a focus issue, but as Frank has already written, motion blur from too low a shutter speed is the likely culprit here. Your lenses are not particularly "fast", i.e. they have a relatively low light gathering capability. The only solutions are to shoot using a tripod or increasing the sensitivity of your camera, i.e. increase the ISO setting. This may not be the best thing as sensor noise will likely become an issue, but if you don't have a tripod, this may be your best option. Try the auto-ISO setting on your camera to see what happens.
As for shooting location, as we do not know the configuration or size of the church, I wouldn't know the best place to begin. The 18mm setting on your lens is relatively wide angle, so you could try to get fairly close. Zooming in from a distance from the balcony is going to be a bit problematic without a tripod.
I hope that this helps...
