The dumbest rod/line/fly question ever.

[Jeffblk72]

Good Day All,
I've searched the magazine and the forums and I'm probably not searching the right way. I have an 8 weight, 9 foot T.F.O. TiCr-X and Scientific Anglers 8 weight Saltwater line I'm planning to use in the many areas of the Chesapeake both salt and fresh. What range of fly sizes and weights is it designed to carry? All my dad did, when I was a kid, was to fish either the popping bugs labeled for bass, or the trout flies, my grandfather supplied with the bamboo rods he loaned or gave to my dad (no, no rods or flies are for sale). Unfortunately, some years have passed, Granddad's passed on, and I have only sparse knowledge in regards to fly fishing as my father has not actively pursued it. Are there any fly/hook weight guidelines to use within the ranges of line and rod weight designations one should use when tying flies and selecting them for use? Any help would be greatly appreciated.
