I would go with the stocking foot with the separate boots. This way you can get a top quality boot or waders and replace one or the other when needed. Many brands out there but price usually dictates quality but once again many may disagree.
8lb Suffix is good line and stay away from the colored lines but not because they are gay but because you don't need to see the main line when running a float like mentioned above.Oh ya,stay away from using braided main line ,personal preference of mine.
Your backing can be a dacron. Just keep in mind that it is a filler and will never be used in battle unless of course you don't have enough main line on your reel for some reason or another...
Good Luck !!
