Call around to your local fish shops and see if you can find some BioSpira. The shops here in Austin have started regularly carrying it again within the last few months, and I know of two that have it in stock nearly all the time now. They both said that it's pretty readily available from Marineland now, so they can get it when they ask for it. It ain't cheap, and it's not an instant fix (it still takes two or three days for the bacteria to really get going well) but it'll do the job very quickly. If you find someone who has it in stock, make sure they keep it in the refrigerator.
Going with the tank squeezin's and filter pad in the old tank for a couple of days will shorten the cycling a good bit, but it still takes "a while" - I wouldn't trust the tank for probably at least a couple of weeks (longer for a heavy load) without outside help like BioSpira. I used old tank water, and took one of the well-established Biowheels from my Emperor 400 and put it in the new Emperor 280, and had pretty much an instant tank - but you can't do that in your case. Also, the denizens of my instant tank weren't delicate, high-dollar fishes (Swordtails and Endler's) so I knew they could tough it out. I still watched the water quality closely, and tested for all the "nasties" two or three times a day for a week. The ammonia and nitrites never blipped, and the nitrates did their usual slow crawl upward.
