Caller ID works right off the bat. It did not work with name at the very beginning (about a year ago) but they fixed that. At that time all had to use a workaround that involved the Contact List. One had to plug the persons name into that and they would show up with their proper name. No more. Caller ID comes up properly. The Contact List can now be used to refine your incoming Caller ID, personalize it even more, as mentioned by DoozerM.
Phones: Definitely worth it. Don't use their link, use the official Sunrocket link for the 2-phone deal

Better yet: Try getting the 15 month deal AND the 2-phone deal combined. I called them last week from my cell in the car and pretended to be a new signup. I told them that I heard that I could sign up for the 15 month deal and still get the 2 phones. I said: "If I get that deal I am sold." He put me on hold for a minute (probably to talk to a manager) and then came back ready to give me the 15 month deal with the 2 phones included. Try it. Not sure if they can still do that, but worth a try or two. Free 800 calls, after all. Be sure to call for SALES.

I like Doozer's suggestion. I would just run with it. Worst case scenario is you get a couple more phones out of it. Have you tried to call their SALES department in Canada? They seem more competent than their counterparts in the Phillipines and can probably see this thing through for you. Must have been a missipment if they show that your package has arrived at its destination.

Sometimes the 2.4 GHz phones interfere with a wireless network, sometimes they don't. The best way to explain it would be to think of the GHz bandwidth as a spectrum. The devices in question (as well as most microwaves, which cause interference at 2.4GHz) are occupying the same spot on that spectrum, 2.4 GHz. However, there may be a small difference when you look further into the spectrum. For instance, your Uniden phones may be on spot 2.401 while your wireless router is on 2.399. Good chance that you won't get interference. If both are right on 2.4 you probably will get some interference.
