Publishers are mostly inconsequential when it comes to old and rare books. The current availability on the market (of the particular edition) and previous sales matter. Keep in mind that the largest portion of published titles have one or two editions. The trick is estimating a book that hasn't been sold ever before. Obscure small publishers tend to be more interesting than the big ones.
Your greatest enemies are sunlight and moisture (read mold). Once a book is infected with spores, the only way to "heal" it is to seek professional help and that can be very expensive (I paid about 300€ for a 200 page book). Unless you are caring for books older than 300-400 years, you shouldn't take any extra steps, keeping them behind glass helps.
