1st 75 does not go all the way to Columbus. You must exit 75 in Findlay. 2nd, yes there is construction on 75 in Toledo.
I75 would take you way out of your way. You would get their much quicker by taking I4.

No, you would get onto I75 a little north of Gainesville. Take I75 SB to either I4 West or I275 South, depending on where in Tampa you are heading.
1010 miles in a straight line (As the crow flies) 1260 miles by road via shortest highway route. (I75 south to FLA Turnpike to US1)
It depends on your method of travel

79 miles
It is, in general, 70 mph. Certain sections, for example the opening leg from Sault Ste. Marie, MI to St. Ignace, MI are 55 mph. Construction zones are 60 mph, or 45 mph when/where workers are present.
Exit 384 is one of them. I think that is Archer.
If you shoot straight up I75, there won't be any tolls.
It is about a 3 hour drive to Starke if you take I75 straight up.
