Yes, usb 2 is backward compatible but will transfer at the sub 1 speed.
A Low Speed rate of 1.5 Mbit/s (183 KiB/s) that is mostly used for Human Interface Devices (HID) such as keyboards, mice, and joysticks
A Full Speed rate of 12 Mbit/s (1.5 MiB/s). Full Speed was the fastest rate before the USB 2.0 specification and many devices fall back to Full Speed. Full Speed devices divide the USB bandwidth between them in a first-come first-served basis and it is not uncommon to run out of bandwidth with several isochronous devices. All USB Hubs support Full Speed.
A Hi-Speed rate of 480 Mbit/s (57 MiB/s).

All in all, mixing the different port speeds is not a big problem. As long as your system and your devices are healthy, you won't run into any issues when working with the different port speeds. Just make sure you follow manufacturer guidelines and you should be good to go.
The main difference between the 2.0 and the 1.0 or 1.1 is that the 2.0 USB ports are faster. It's pretty much as simple as that. USB 2.0 averages a data rate of 480 Mbps (megabits per second) while USB 1.1 only hits 12 Mbps.
However, some devices would not work with USB 1.0. In this case, you may need to install a USB2.0 PCI card. For more information on this :

Yes but the device will function at the slower usb 1.0 rate. If the devices is a cd or dvd burner this may affect it somewhat but items like a flash drive or camera you shouldn't experience any problems.
