you got most of what you need.
do some research on the mixolydian, and, to a lesser extent, the dorian

but mostly make sure you know how to use them. anyone will tell you, the blues aren't about what scale you're using.

Over A7, yes. When it changes to D7, you'd want to avoid that C# note, though you could play the D major pentatonic over D7.

You could use A major pentatonic over E7 as well, though there may be better names for it in the context.

I have a longish post about how all 12 tones work over each chord in a blues. If someone finds that, please post the link.
