First, according to Roberts Rules, the person who proposes a motion must be identified in the minutes. The person who seconds it does not. The vote of the indivudal members does not have to be recorded, unless a member requests a roll call vote, which then requires a majority vote to pass, unless there is a provision in your bylaws requiring it to be otherwise. Requiring a roll call vote by virtue of a majority vote is kind of useless, since the purpose of requesting a roll call vote is to force the majority to go on record as being in favor of a motion.
As far as abstaining goes, that works against you. An abstention is no vote at all. It isn't counted (refer to Robert's Rules). If the bylaws don't stipulate otherwise, the vote is counted according to the number of votes cast. So, in a 5 member board, if two abstain, then there are three votes cast. If the vote is 2-1, then the motion passes. Thus, by abstaining, the two members who abstained have allowed the motion to pass by only two members who voted in the affirmative. Not good.
On the other hand, if the by-laws require the vote to be counted by the number of members PRESENT, then, in a 5 member board with all members present, if 2 members abstain, the same 2-1 vote would fail. In this case, the two abstentions have the effect of a no vote, but they ARE NOT COUNTED AS SUCH.
The best way to maybe handle this is to modify the bylaws, not to require that every vote include how each member voted, but to require that a roll call vote be taken if some minority (like 1, or even better, 2 members) requires it. This kind of takes a middle road approach.
Some states require that it be part of the record as to how each member votes.
