I like that you are considering the entire package as part of your negotiation - that is smart. Base salary is only part of the equation.

When I negotiate in these situations, I think about the most important aspects TO ME. for example, vacation is more important to me than base salary, so I will push that over a number. Also, NEVER count on profit-sharing or bonuses. These are a nice BONUS if they happen, but should not be considered as part of your thinking, in case they don't happen for whatever reason.

Also, I would have these conversations verbally vs. via email. While negotiating a new package is difficult (and as women, we are generally very bad at it), it is best done face-to-face.

Just my $0.02, FWIW. Good luck!
