I'm holding a decent amount of NXT tokens. What do I need to do to participate in this "snapshot"? Where do I find information on converting these to Ardor tokens?
Absolutely nothing, hold them, they will be automatically converted. It's preferred that you store your tokens in your account, not at an exchange. Exchange is a risk, while the Nxt platform will convert tokens, the exchange still needs to give them to you. Some exchanges default on their obligations, Mt.Gox, Cryptsy.
Also, based on the "sell the news" philosophy which seems to be the case almost 100% of the time, would it not be better to sell the NXT tokens on the exchange before the Ardor release, then just buy Ardor after the dump?
What date is the Ardor dump?
