Question 2: Isn't there a way to create Amiga compatible floppies by using 3.5 floppies by formatting from a PC running Windows?
To actually write floppy disks, you'll need a catweasel board and a floppy drive in a PC. I don't think Jens is making them anymore. I have one and they're nice to have, especially if you have other retro hardware. But it's an expensive solution.
Assuming you have some workbench disks to get you off the ground, there's ways to transfer disk image files over a serial connection and write them with your amiga. This can present a chicken or egg problem.
There are also a couple of devices available now that allow you to replace the floppy drive with an sd card reader. You select the disk image on a little lcd display and the amiga is none the wiser.
I think at this point the best solution would be to pick up an ACA500. You can use WinUAE to create a bootable workbench hard drive on a compact flash card, then boot the 500 off the compact flash card. Then you can use another compact flash card formatted for fat32 to transfer image files.
