Answer 1

Firstly you should ALWAYS validate server side for form submission, especially if you are passing those value along to a DB - SQL injection, the struggle is real.

As for the form submission flow you can...

return true

... after the valid name alert and the form to submit as it normally would.

Since you already have bound to that submit event, It would be even better for the user if you submitted the form via ajax, and providing feedback if the server validation fails. Thus the user never leaves the page and you are able to handle both client and server validation.
