Right question 1, no you can't really tell the difference between them in winter, UNLESS you've not touched them since flowering, there may be clues at the top of the bushes if the faded flowers are still there. Hybrid T' will have a single flower head, floribunda's multiple heads left. Otherwise you won't have a clue. Roses go leggy if they aren't prune correctly, hard pruning is beneficial to all roses including climbers as new stems produce the best flowers.
Question 2, the more sun you give roses the better they like it, but 3-4 hrs a day is adequate, although some of my roses get a lot less and still thrive, It's more to do with keeping them well fed and watered than anything. Roses aren't deep rooted, unless they are very old, 18 inches of soil is fine. Roses can even thrive with poor drainage as long as they are fed well
