Which Lion-compatible HP LaserJet MFP printer to buy?

Hello everyone from a just-registered newbie! I am completely switching from my Dell desktop PC to all-Apple everything very soon. I want to complete the process glitch-free(don't laugh). I will purchase an Apple MacAir and Time Capsule (router+HD combo) for home-based wireless connectivity. Which HP LaserJet all-in-one MFP for home use would be a wise purchase? It must, of course, work seamlessly with the Lion OS and support AirPrint. Should the wireless printer chosen ALSO have an ethernet connection in case I want to occasionally use it non-wirelessly or is this a waste of money? What features on the MFP have you found you cannot do without. I will get an iPhone later once I learn the functionality of the initial purchases. Many thanks in advance for your patience with a newbie. I apoligize for this "dissertation". This forum will be a great resource for me. I appreciate the practical expertise of all those postings I've seen thus far. Happy New Year to all!
