Usually suggested for Member equity (even a sole participant of an LLC is a member instead of owner but that is not important) is a set of 4 equity accounts per member.

What you have is certainly workable and I would not change it to change it.
OBE is only used when first setting up books. At end of first year that should be transferred to Equity although if you still have OBE you probably did not properly pay off the former partner their fair share.
You do not have to zero contribution and draw annually on first day of new year but it can be helpful to keep track annually of personal funds movement. Otherwise these accounts certainly can always have a balance.
At year end profit or loss is posted to RE. From there it is distributed as equity increase or decrease to all members based on their ownership. In your case 100% of RE should be transferred to OE.
