No, the 2.5mm is correct.  If you'll notice, that applies to the coaxial 
power connector.  2.1mm and 2.5mm are the two standard center pins

Yes.  I didn't have the exact frequency on hand last night.  I plan to 
socket the crystal, and the clearances are for a standard HC-49 sized 
footprint.  I may put a set of SMT pads down adjactent to it.
