It won't have any effect (or shouldn't). When the House finally passes the bailout bill, credit will open up (or should at least). Things are being held up right now because nobody knows exactly what the bill is going to be.
Disney shouldn't have a problem financing this regardless. What could change the plans, though, is attendance and profits. If business tanks at the resort, the blue sky plans (or some of them) will likely change or be put on hold.
I hope not though, I am welcoming the changes to DCA. I attended the cast member preview (my sister was in one of the shows) and was totally disappointed right off the bat. It was very clear that they skimped all over the place, and in many respects it was a big advertisement for ABC.
