da_clicks - Welcome to WW! I also have seen a very large drop in PFI pages while free crawled pages are stable. It's still unclear what is causing this, but there seems to be direct correlation with pages being PFI and getting filtered out.
And yes, Ink is also having trouble indexing dynamic links. There is a thread about it here.
I think paid inclusion is a good idea, I would recommend that you definately wait a while until Ink settles down and figures out what is going on before you drop that much money into PFI.
Read about the PFI providers here and in other forums around the web before you settle on one.
