Pine is nicer than hemlock, from my side of things. If all the sapwood is sawn off you will not get blue stain. But you need bigger logs for this to happen. Soaking the logs in a pond helps with eliminating blue stain, too.

Sticker stain most likely won't plane out, it seeps into the timber a fair bit, 1/2" or so. Yes, dry stickers, saw in the winter, and keep dry.
