yes, sprint got rid of it's free incoming plan.
direct connect is the walkie-talkie style communication, which is only usefull when working with a group of people on say a job site, where everyone needs notified, otherwise it's a glorified way to make a phone call. (mostly for nextel converts)

good luck getting a diamond, as far as i've know, there are no reservations, but work with a local store and you may get lucky and have a rep hold 1or2 for you when they come out. you'll also need to work with them for the best option for your plan, as i'm not sure what data options are available on the lesser minute plans. I'm on an old plan and unlimited data was only $15 per line.

good luck, welcome to the site & USA!
