I honestly do not know much about the differences in the two IOSs that you mention because I have never worked with anything below 12, but I wouldn't want to take the chance that there were.

As for a switch: Yeah, you need one at least, to do any kind of vlan config. VLANs are important for the exam and for real life. You can get a 2950 cheap on eBay.
