It would be very helpful if you would put your location and zone on your page so it will show up here. If not please at least give us some idea of where you live. It makes a difference! I live in Michigan and you may be in California. Those are two very different climates!
I'll try to give you some general information but it will depend some on your location.
1. If you are planting them in the ground any good quality garden soil will work (I've used the one at Lowes before and it was fine) but with clay soil you will have to dig deep and do a drainage test first. Dig your hole and then fill it up with water and walk away. Come back in an hour and see what happened. Is the hole empty of water or still full? If the hole is empty or nearly so you're good to go. If there is still a lot of water in the hole you need to dig deeper and repeat the test until the hole drains. Roses like a lot of water but will die if their roots are sitting in a pool of it all the time.
2. Any well balanced fertilizer will work. Follow all the directs for how and how often to apply it. You can add organics to feed your soil at any time. Organics are things like composted manure, fish emulsion, alfalfa meal or tea, that kind of thing. Any thing that is good for the soil is good for the roses.
3. They mean chemical sprays for insects and diseases on the back of the tags. You may or may not want to do this. I do not use chemicals sprays in my garden. Too many of them kill the good bugs as well as the bad but that's a personal decision you'll have to make.
4, I always give mine a granular slow release fertilizer, scratched into the soil, in the spring when I prune. After that I use liquid foliar fertilizers (Miracle Grow, Spray n Gro, whatever I have) according to the package instructions. You don't need to over do the fertilizer. You can actually kill a rose by over fertilizing it.
5. I don't know of any rose that will grow and bloom properly in less than 6 hours, and preferably 8 hours, of direct sunlight! I don't know who writes these instructions but they don't grow roses! It sounds like your garden will be fine.
6. Try to remember to relax and enjoy your roses, lol! Roses are survivors. They will over come lots of obstacles to grow and bloom. You really don't have to fuss over them all that much.
