Welcome to the Q&A Forum

I believe, and have heard,  although i haven't proved it, that Google thinks of pdf's as technical content, which is very good for SEO. That said, its probably good to have a brief html text entry for the pdf, with a link to the pdf. That way you can summarize the content of the pdf, add value to the content of the page, make it relevant etc... But then perhaps you have to consider duplicate content. I believe you can add meta to the pdf if its editable that way, and consider if it is duplicate content, then make the html page meta canonical, and establish the pdf as the original.

Thanks for that link, I wasn't aware of it. Yes, I'm trying to get the redirect you mention taken care of. If only the client could tell me who maintains their website!

Sorry. I just noticed that my link in my earlier response was broken. Here is the correct links http://bit.ly/feg8co

About relevancy yes, you should include some variations of with Location Title Tags.
