Restart your mini and hold down Command+R during boot up. This will boot the recovery partition where you can do a new install of OS X.

Can I just reinstall Yosemite or do I need to go into disk utility first to erase the disk?

It sounds like your purpose is to do a clean install. Boot to the recovery partition, use Disk Utility to wipe the drive, then install Yosemite. You will have a clean install as new.

You need a DDR3-1066MHz 204 PIN SODIMM. I recommend these guys, as they really know Macs well:

If your firmware is up to date, you can install up to 8GB. If you don't do Apple's updates, you might have an older firmware which can support up to 4GB.

Also how can I install maverick for the time being
I don't understand, what operating system are you running? The recovery partition is created by whatever version of OS X that you last installed, and should only be able to reinstall that version. So if you have Mavericks currently installed, the recovery partition should reinstall Mavericks.
