Kendall.Shaw> yah & $a+b$ \\
Kendall.Shaw> \end{tabular}

Kendall.Shaw> I imagine this has to do with it being the baseline that I'm adjusting. But,

Kendall.Shaw> Also, is there an easy way to adjust the baseline properly rather than

You are right that the management of inter-row space is not exactly
what we can expect. Even in your first case, we loose the vertical space
above the frame. I cannot give you the real explanation, but this is
rather unusual to include graphic objects in such environment (for instance,
PSTricks has his own environment "psmatrix" to position text and graphic
objects on a grid, with a lot of additional capabilities - but this is
probably not what you need in your case, as you explained before that you need
to use the "longtable" environment) and it can generate some unexpected
effects. This is not really specific to PSTricks, and you can verify that the
result is the same if you use the standard LaTeX environment "picture".
Nevertheless, the simplest workaround for you is probably only to load
the "tabls" package from Donald Arseneau (one of his numberous useful tricks).
It will automagically greatly improve the situation (and even you can control
it effect).
