Creating Sample Packs

Hello everyone. Had a question in regards to creating your own sample packs. I have some understanding of the process of making sample packs (zero points so there is no artifacts, from scratch samples, normalizing or making the samples in the pack relative in level, etc). However I was curious if there is anyone out there who has or knows of a list for a creating your own sample packs 101 so to speak, that has the uniform guidelines for this process? Also a specific question I have is do you master process your samples after the mixing process? Have some understanding but would like some more guidance if anyone can help.
