Repaired Mac hanging when restoring

Question

Got my late-2011 MBPro back from repair, where a new logic board was installed and prematurely dead battery replaced, "latest registered operating system"(was told that'd be 10.8.2) installed but no new hard drive installed (allegedly). I asked the clerk whether that meant I wouldn't have to restore from my Time Machine backup and he confirmed I wouldn't.
Got home, plugged it in, booted up and....WRONG!! Was taken to the startup screen that shows up on a new Mac, asked about language and keyboard preferences, and whether and from where I wanted information transferred.  It took me several tries to connect to my home network and find my Time Capsule, and then four or five tries before the name of my most recent backup showed up in the source list. Clicked on it, and got a screen with types of items to transfer--all of which except "Settings" were indicated as "Calculating." I got tired of nothing happening after 10 minutes, so I clicked on "Continue" and got the "Transferring Your Information" screen, which for the past hour has been hanging first on "transferring your documents" and now "looking for documents and applications to transfer." Finally switched to "Transferring Documents," but the blue progress bar is still endlessly striped like a barber pole. And it's listing the estimated time to restora as "About 153 hours and 52 minutes remaining."  Of course, Apple Care is closed for the night. (Don't they know how many users are night owls who save this stuff for AFTER work and family??????)
What the....? Last time I had to restore from Time Capsule (on a previous MB Pro) the machine started up,  
PS--now it's up to "158 hours and 36 minutes...."

Oh, God. Just did some more reading (in Mountain Lion and Time Machine) and it looks like I messed up BIG TIME (but nobody told me how to avoid that).  I went through Setup Asst. after the "transfer information" progress bar kept hanging and the last time estimate had climbed to 180 hours--so I skipped the transfer process.  I had NO intention of setting up a "new account," but because my MB Pro thinks it's a new machine (or has a new HD) when I entered my existing username and password it set up a new account anyway!!!!  Went into Migration Assistant to restore from the TM backup on my TC. Even though NO other devices are accessing the Time Capsule I keep getting the warning box saying "some backups cannot be accessed," and no matter what I do the only backups recognized are of THIS machine (the MB Air).
I DON'T want to take the MB Pro back downtown to the Apple Store to have them reinstall Mt. Lion yet again, and I certainly don't want to have to haul my TC along too.  What the heck do I do? It's Apple's fault, because they did not warn me the hard drive would think it's a new machine (Setup even asked me to register!!!!) and did not warn me what and what NOT to do to restore from my backup. Heck, they even told me I wouldn't NEED to restore!!!  It seems every time I get a Mac repaired I go through hours of grief and frustration followed by a sleepless night because (unlike at other tech support facilities) Apple doesn't believe in 24/7 tech support.
And now I'm going blind typing on this little MB Air (which is my travel notebook)--and am missing all the files I need.
Meanwhile, doesn't anybody HERE stay up late?????
