If you're planning to dive in the UK, I'd also suggest going with the SS plate (and probably holding off until then before you buy). Thicker exposure protection, especially if you end up in a drysuit, means you'll need more ballast to sink....when diving a single tank, I dive a small SS DSS plate with the additional weight plates (total weight for the plate is 10 pounds) and then four additional pounds on a belt.
For reference, I'm 5'2" and 120, so pretty similar to you, it sounds like. The small plate isn't a big deal for me when I dive singles, but it makes a noticeable difference for me diving doubles. Sounds like you could probably go either way.
FWIW, if you're going to stick with warm water, an Al plate is likely your best bet....as TSandM mentioned above, you can add weight if needed, but there's not much you can do if you're inherently overweighted (a few pounds is not a big deal....much more would be).
