Congratulations on your purchase and welcome to the forum. I recently purchased a 2014 with no experience on previous models so can only answer question #4.
From 2007 manual:
Autostick operation is activated in the D position by
moving the shift lever side to side. Moving the lever to
the (+) side will activate Autostick and shift up to the
next higher manual ratio, unless you are already operating
in or near overdrive in which case, 6th ratio will be
selected. In like manner, moving the lever to (-) will
activate Autostick and shift to the next lower manual
ratio. After Autostick is activated, the manual ratio
selected is displayed in the transmission ratio display
and tipping the lever to the (+) or (-) direction will cause
an upshift or downshift by one ratio. Holding the lever to
(+) momentarily will deactivate Autostick. Autostick is
also deactivated when the lever is shifted out of D. Also,
when in 6 position, touching the lever to the right will
restore Drive D position.
