The only taxing game I see on that list is probably WoW, the others I think are low quality 3D like Runescape, and will probably run on the Netbook.
The first thing I would do is update the video drivers.
First, click the Windows Button/Start Button.
Second, in the search box, type dxdiag, and press enter.
In the Display tab, you should be able to view the manufacturer of your graphics processor. I'm going to guess it's Intel though, if it's a weaker laptop.
Then just go to their website and obtain the drivers. It's as easy as selecting your product and getting the downloads.
