While AA weaving is important, there isn't a set number of AA's you should have per spell cast. It's more of a feeling around for the right pace. If your lanemate has any sort of cc, you typically want them to pop it as you're going in so that you can close on them without them sprinting back to their tower. Remember that while the second half of your q is a gap closer, it also functions like an execute (8% of missing health added in damage). With that in mind, you can w to a minion, e for the slow, q, step around the champ, kick them in the face, q back to them for more burst. Otherwise, you usually just lead with your q and attempt to burst them down with your lanemate's help.
