There is Lakeshore Camera Exchange in Palm Harbor , just north of Clearwater and Pasco Camera Exchange in New Port Richey a little further north.
They both have darkroom stuff and film etc, also sell some used gear. Lakeshore has a lab, not sure how much they still do in house though.

I stop by both places now and then to pick up a few items such as chemicals etc. Sure, they may not be like the camera stores of old, but at least they still try.

Hope this helps
