I have never worked with teak before but have read a lot about it over the years. I have to quote a job that will involve re-sawing in half about 700 board feet of 4/4 teak and running it through our planer sander to 5/16" thick. We will then cross-cut to length. I know teak is abrasive and hard on tooling. Should I figure in a blade or two for the 32" bandsaw and insert knife fee for the planer/sander and chopsaw blade fee?

You will want to use a carbide tipped band saw blade and carbide knifes for the planer. Teak will dull steel in a very short time.
To mill teak you should really have carbide in everything that touches the wood, even a few hundred feet through HSS will pretty much destroy it. If the job doesn't justify the expense, you should probably not to do it. I've heard stories about people who didn't understand what they were getting into and lost money as a result.
If you can avoid sanding teak below 100 or 120 you'll be much happier - at finer grits it loads rapidly. Slow feed rates, passes no more than .010 and constant cleaning of your rollers help, but it will load your belts and coat the inside of your sander with waxy dust. It doesn't burn easily, though, so you can get away with using dull belts.
In sum, be sure you account for the substantial expenses involved in milling the stuff or you'll kick yourself for taking the job. It mills cleanly and isn't fussy, but that is the only positive thing one can say about it. The dust does bother some people, but I don't find it offensive, I have more reaction to cedar.
