Help with Florida and Georgia trip!

[minty]

Hi all, I hope you can help me! This is my first post on this wonderful site (I've been a lurker for ages!).

I have a couple weeks to take a little trip around Florida. The first half of the trip, from Key West to Savannah, is taking shape, but it's the return leg that's giving me problems - there's only so much I can find out from here in England, and I'd love some local knowledge to help me out. I'm not rushing, I'd much prefer interesting back roads to Interstates. Here's my (rough) 4 day plan:

1. Savannah to Tallahassee: It's been suggested I avoid the 'fast' route via Jackson and the I-10, instead going via Waycross and US-84. Is that good advice?
2. Tallahassee to Tampa: From the maps, US-98 seems a more interesting route that I-75.
3. Tampa to Naples: Again, US-41 looks preferable to I-75 - but is this an empty road or one full of local traffic?
4. Naples to Miami: Again, is US-41 preferable to the I-75?

Also, I'm not dead set on staying in Tallahassee, Tampa or Naples. I prefer small towns to soulless city downtowns! Presuming I keep roughly the same route, are there better places to stop/stay? I could also add another day to this leg if need be!

Many thanks in advance for any help you can offer!
