Sierra Nevada bottles are some of the easiest, just need the right tool for the job. A soak in warm water with OxyClean (unscented) or PBW will have the labels off in no time. Might have to hit them with a green scrubby to get the glue off, but it will come right off.
Moldy bottles usually aren't worth the effort. I had a friend give me a bunch of bottles he'd kept in an outbuilding. Many hadn't been rinsed and there were all sorts of things in there. By the time I realised how bad some of them were, I'd already started cleaning them and decided to persevere. Even the worst gunk comes clean if you dump a spoonful of OxyClean and some hot water in there, but probably not worth the effort.

and i dumped the priming sugar/water solution in my bottling bucket w/ spout.
im thinking of getting the pint bottles and yea probably the ones w/ the cork tops, im assuming that is what you mean by the swing tops?
