There's is a cost calculator on the DMV website to give you an exact cost. $2-3k in registration expense would mean you purchased a car for roughly $30k or more which doesn't sound accurate from your description.

Don't feel like I see this one get mentioned often, but Taqueria Cachanilla on S Glenstone has excellent tacos. Tamales are fantastic as well.

Did not see Casa Bella in this thread, wouldn't say its the most authentic, but it is delicious.

Wal Mart on Independence has Vaccums out for Black Friday deals, $59. Good luck OP!
