B) put the SSD into the 2nd bay, tell the BIOS to boot from the other sata slot first and then load the OS.
C) There are drive caddies that can replace your DVD drive with another drive bay. This shouldn't be needed if you have the version I'm thinking of.
I personally have a 256GB Samsung 840 PRO in mine which is a 7mm drive. There should be plenty of room to fit a 9mm inside of the bay but the Crucial MX100, MX200 which will possibly be out soon, and ones like the Samsung 840 Evo for the lower sizes all come in 7mm heights.
They've made reloading in Win8 both easier and harder depending on what you want. The COA is typically stored in the BIOS now so it shouldn't have to be manually input. Using a Win8.1 OEM disk, the wireless drivers were automatically installed which made getting the rest of the drivers quite easy by going to the manufacturer website. The companies often ship their SSD's with migration software to essentially port your old OS to the SSD but I've run into issues with this a few times which was rare but quite annoying. So I tend to suggest fresh loads on the SSD. This then also allows you to get rid of a lot of the programs that meant nothing to you or haven't been used in years. As a reminder *some* professional programs require you to deactivate the key used then reactivate it when you put it on another computer. You would probably already know this if you have such a program, but just in case. For extra security you may just want to make a full backup onto an external drive/a cloud service for posterity sake and the fact that it's just a good idea to backup your data.
Upgrading your ram will not typically have any performance increase for the games you run unless you like to run a lot of programs at once and force the PC to start using the page file. Even a ~20 tab browser with 2 WoW clients open didn't max my RAM (was at 6GB used of 8GB). The EVO and MX100 are both solid consumer drives. I wouldn't suggest anything under 256GB though as even just WoW and TOR are between 30-40GB each. Some may suggest against the EVO because of a firmware update you may need to do, but it's easy and typically harmless.
