Markus Jayne has a great page on breeding that explains how they do things. I used this as a reference last season and successfully hatched a clutch of 5 eggs.

Males can breed much sooner than females so getting two adults would let you breed sooner, but if you get a morph girl and raise her up you could produce a combo. There are lots of things you can pair a spider with, mine will probably be going to my butter this year and maybe my lemon pastel.
