From the system requirements for Windows Server 2008 (on wikipedia.org):
- Minimum: 512 MB RAM (may limit performance and some features)
- Recommended: 2 GB RAM or higher
I'm going to have my website hosted on a Windows 2008 VPS and I was initially planning to use a hosting plan that gives 512 MB RAM (to save some money), but now I'm worried, do the same system requirements apply to Windows 2008 running in a VPS or are there differences? My website has very little memory requirements but I'll be using MySQL which should use some of this memory, should I get at least 1 GB of memory?

You have to measure. These guesses will serve you no good.
I'd hire a 512 MB first, stress test it and if proved that RAM is the bottleneck to achieve the required performance level, then bump up the contract to 1 GB and measure again.
Don't know if all hosting providers will allow you to upgrade at will, but it seems like a natural requirement to me so you shouldn't have trouble finding one that can do it.
