The plug will go in without even loosening the radiator bolts (at least it did on my 426) but it's way easier to install the seal with the rad removed. If you removed the bolts but left all the hoses hooked up, you could probably get the seal drove in with a long enough extension, but it's much easier just to drain and remove the rad- it only takes about 15 minutes.

You mean the stock plug? I would dig it out with a pick- it shouldn't be very hard to remove.
