What is the usual process for a paper after getting accepted? Can you still make edits for readability?
Depending on the journal, one of two things may happen after acceptance:


For many journals, once the paper is accepted, that's the last time you touch it: at that point, the journal staff stick it into the production queue and in a few months it appears in a new issue with page numbers and citation information added.
For some "fancier" journals, the production staff does more extensive reformatting to make the paper look pretty and copyediting the text to correct such minor errors and make sure everything is in conformance with all of the journal's preferences for style.  In this case, you will work with the production staff on the final proofs, approving the copyedits they make, and may be able to insert a few minor changes (but generally just wording, not substantive technical changes).


This is further complicated by the fact that some journals now have an "Articles ASAP" or "Just Accepted" publication, which puts a preprint online before copyediting (flaws and poor formatting and all), and only later replaces it with a final version.

Bottom line: unless you know the journal does copyediting and has no "Just Accepted" stage, you should correct all of the flaws you notice now.
