Simpson - I think MM is right, it sounds as though M, with her very clever little brain (wow, am so so so impressed by her spelling and writing...) has figured out that is isn't as 'simple' as just practicing more in order to be able to do things. I know you do it already, but can you find a way to focus on the things she is good at, like the reading/writing, so she knows that she is really special and amazing too?
Also (just a thought, can't remember if we've discussed it before) are you able to take M swimming? I've found it really helped A & T with muscle development, and it requires a different sort of strength and ability.
Finally, I'm also really interested in M's writing as A & T (esp T at the moment) have really struggled with the whole pen/pencil holding thing due to their hypermobility issues. T seems to have mostly grown out of the 'leg' part of the problems (although mastering skipping, hopping, balancing is still harder for her) but really struggles with the fine motor skills for writing.
LaT - great cakes. They look quite easy, in theory, although I'm better at baking complicated shapes and using buttercream icing, than doing fancy stuff with sugarcraft...but it shouldn't be too hard to replicate. In my experience, its actually easier to do everything using sugar rather than trying to use plastic toys on a cake, as its hard to get the 'scale' right, and remarkably easy to make the right shapes with the icing :) I still like making the right 'shape' cakes, partly because the molds are so bloody expensive (lol @ another pirate party JKS!) and partly cos I don't think they're big enough.
JKS - if you change your mind, I can send you the cardboard templates I use to build my pirate ships? Its just 2 flat tray-bakes that I freeze to make them easy to cut, and then cut into the right shapes and put together with icing, like lego.
LaT - if you work out the basic shapes you need, you can 'build' almost anything, so you don't need lots of fancy molds, if you get really into the whole cake-making thing :) I have only used my 2 big rectangular baking pans (and a pyrex bowl for the fairy's dress) for the last 6 years, to make everything Filly in total denial of the stress involved in creating Thomas' funnel in a baked bean can
