The plains mine was mostly 'something to do' while roading over and getting ready to farm the wheat, so sure, drop it if you'd like (I can't remember if that affects any build timings, but you're probably not going to be following what I did, anyway).
If you're sending the worker outside our borders, I'd keep the scout nearby (or, you know, count how many turns you can have him away), especially given the demonstrated presence of Sith Lords nearby; otherwise, I have to admit I'm curious about the south, but maybe that's something a warrior should scout out later given the rough terrain will prevent our scout from taking full advantage of his mobility. Up to you.
