I typicaly dont use any 'protection' filter (and the sensor already has a UV filter built on btw...) , tho I will throw one on in poor conditions or when shooting surfing etc.
The front element of a lens is usualy very robust.
If you buy one buy aproper multicoated decent priced one to minimise the IQ degredation you will suffer.

Worms, can, opened 
I've always used them, along with lens hoods. Many others say its pointless, but I've had stones kick up at motorsports events and hit the front of the camera - so I fit them on all of my lenses.
I've always bought the worringly expensive Hoya Pro filters - normally at the same time I buy the lens so the cost doesn't seem quite so bad
No point spending all that money on the lens just to put some non-coated cheapo filter on the front...
As your 15-85mm will be EF-S you might get some vignetting if you don't go for one of the thinner rimmed (and normally more expensive) filters. Might be worth popping to a camera store and trying a couple to make sure

Hi Rob - cheers, so basically they are purely for physical protection of the lens if the sensor itself deals with any UV issues ?The front element of a lens is usualy very robust.

Sorry my IQ must have degraded substantially as I don't know what the last bit is about

Ah - it's one of these is it!? Sorry I didn't know I've always used them, along with lens hoods. Many others say its pointless, but I've had stones kick up at motorsports events and hit the front of the camera - so I fit them on all of my lenses.

I am a klutz and would be distraught if anything happened to my new lens so I reckon I will be getting one. How about summit like this

Yes all digital sensors (wel bar the Leica M8, oops..) have a UV filter fitted otherwise blacks apear purple etc. Sometimes the UV levels can be quite high and an additional one (if the cameras own is weak) is appropriate, but rarely.Sorry my IQ must have degraded substantially as I don't know what the last bit is about
As to the second part - each air/glass interface can introduce abarations, softness, distortion, flare. A filter introduces 2 new air/glass interfaces.
Making the filter properly, coating it with anti glare coatings etc all improve the filter and reduce the chance of it affecting the image quality.
But it cant improve it so your realy looking at doing as little optical harm as you can.
And as above there are valid reasons/situations for using them, I just dont think there worth it most of the time.
