Almost certainly.  BTW, pretty much all the tires I see have sizes ending in '5'.  I'm pretty sure you really mean 185/70-13 and 185/80-13.  The latter is fairly close in diameter to the stock 6.50-13.

Yep.  Early speedo drive is off the transmission, so that should work.  I'd start by doing that and then re-check to see where it's at, there are a couple different speedo drive gears if you want to adjust it further.
