2)This question refers to YECs. The fact is the radiometric dates aren't always remakably consistent with each other. It is more likely that three different dating methods on one sample will yield three different "dates".
JM: How do you figure? This is demonstrably wrong ( http://gondwanaresearch.com/radiomet.htm ). This is but one example, consistent dates are legion. However, with your sleight of hand this could be true. For example, we know that different systems have different closure temperatures. So let's say we date a granite with U-Pb, Ar-Ar on hornblende, Ar-Ar on biotite and Ar-Ar on K-spar. We will, indeed, get different dates. Is this a slap on the methods? Hardly! From diffusion experiments, we know that the closure temp of zircon is above 850 C, for hornblende is is ~500 C, for biotite ~350 C and K-spar contains a domain structure that has been investigated. Domains begin to close ~350 C and continue to close to the Ar-system down to 100 C (Meert et al., 2001; Gondwana Research; Meert et al., 2001 Tectonophysics contain examples and further references). There are two interesting points about these experimental and field results. The first is that we are able to document the cooling history of a pluton. Secondly, we can study the magnetic signature of the pluton (also temperature dependent) and obtain an age for the magnetization of the rocks. The correspondence between magnetization age and independently correlated magnetizations is excellent.

3) Who said "all the fossils were laid down in one Biblical Flood event"? Death occurred before the flood and continued after the flood. Also not everything that has lived and died has become fossilized and we haven't looked in every place for these fossils. What if what you seek is under the Antartic ice cap, well below the land surface?
JM: Well, a number of your creationist brethren have claimed this in the past and present!
