Hi Diane,
You'll likely want (or a moderator will do so for you) to have your own thread as you might get overlooked in this one.
As mentioned above, slate usually drastically ranges in size, so you'd be better off having no less than 1/8", but usually you can lay out eight or so in a row with a joint that looks good to you and get an average layout for two tiles. Slate does absorb quite a bit, so sealer for exterior is absolutely necessary. Try to stay away from the shiniest of sealers, as they could make it slick when wet. Try reading up on AquaMix's options for slate. You'll may need to call their technical people to ask about compatibility with the Homax stuff. You definitely want to use sanded grout, and a grout release or presealing would make clean up much easier. When installing outdoors 100% coverage is key.
