I need to edit an alpha channel for a texture I am making, but don't have access to photoshop. Can I alpha edit with paint.net?

GIMP is the best choice for this case. It's free and user-friendly. There's also a plugin which lets you open and Export files to .VTF, although I wouldn't be using it to Export as it generates different effects to the ones when using VTFEdit.
