The spring rolls sound like a winner to me! A Gruner Veltliner goes well with Thai. Mostly something with a bit of sweetness is what comes to mind - like a light Riesling...a kabinett versus a spatlese or auslese. I prefer a troken (dry), but, that's just me. A fruit forward pinot grigio will also work.
As far as a salad if you google Thai Salad Recipes you will come up with some good ideas. I like the cucumber salad with some spice to it. It also will be easier to make than the spring rolls and no flying grease to clean up
