It sounds like you are making good progress so far so well done on that. The sequence of training I would suggest to someone in your position would be:
A 1 day foundation course in your chosen standard(s)
A 2 day Internal Auditor course (preferably IRCA registered but not essential)
A 1 or 2 day 'How to be a quality manager' course
These should be done in this order and quite soon after taking up the post.
Then, some way down the line (at least 6 months) consider a lead auditor course
