One thing for sure is you won't be dissappointed in the lens, for it does a great many thing really well. Even if you find it less than ideal for interiors I doubt very much you'd sell it but rather save up to supplement it with something faster, because there's no substitute for that, when you need it.
For the record, I have the 17-55 IS and don't have one speck of dust. I came to the conclusion that the dust thing is more a problem of principle than of anything else, not least of which is image quality. Do I wish it could go longer sometimes? You bet. Do I wish it were weather sealed? you bet. Am I glad to have f/2.8 & IS and be sharp wide open? You bet!
