I am thinking about filing for the PPA so I can get the "Patent Pending" status. Can I market my invention in this status and be safe? I mean the regular patent application process can take up to 2 years. My concern is that since my application is in pending status, what if someone else comes around and files the accelerated patent application, will that ruin my invention?

I want to start aproaching manufacturers as soon as possible. What are some of my options? I would appreciate any help.

A PPA gives you "patent pending" status showing that you started the patenting process and it records an official date of conception for your invention. If you file a regular patent application within 12 months you use the earlier date as proof of conception. Once you start the patent process does not matter how long it takes until you see the patent issued, you have the proof from day one. Anyone that will obtain a patent for the same thing will have his patent invalidated.

This is why when you talk to manufacturers you have them sign a "Non-Disclosure/Non-Compete Agreement"
and also you don't give any details about your "patent pending" or patent application until the moment they are ready to sign the licensing documents.
