A sample photo is always a good idea. We should easily be able to tell if it's a shutter speed/camera shake problem or if it's actually a focus problem.

For filters, you need to know what filter size. I looked at the Canon and B&H Web sites and it looks like you need a 58mm filter. The 52mm filters would be too small. The only kind of filter that's really useful with a digital camera is a polarizer. Anything else is more esily done with software in post-processing. But the polarizing effect can't really be replicated with software.
