As for conversion to 48 khz, if this is not done well, much of the advantage of using digital audio will be negated. While resampling can never retain the same quality level as the original file, the degree of degradation can be vastly reduced with a high quality algorithm. The iZotope processor (which I have) may well be one of the best ever made. Very few others can come close—even the ProTools resampler isn't quite as good as that.
Are you talking about plain resampling, or more of a "stretch and pitch" process? Plain resampling from 44.1 to 48 with even a naive algorithm is going to make no audible difference, surely? iZotope and the like are for mangling pitch or duration without affecting the other - what kind of difference in running times are we talking about?
