Going rate for Toyos fitted depends a bit on where you live. Up here Black Circles are more competitive than other parts of the country and £280 - £300 is the rate for 4 fitted. I like my Toyos (16 inch rims) although they won't last as long as some other makes.
Clutch thing is annoying. For any distance in the MG, I wear flat and narrow shoes which helps a bit. I've also fitted the seat lowering springs (only 2/seat rather than the 4 supplied) and they do help a bit but not a lot really. David A has gone to the next step by fixong the seat directly but only if it's a single driver car and you don't plan to sell it in the foreseeable future.
Think carefully about black leather seats. There were several posts this summer about the lack of breathability and the need to either have aircon, a change of pants or drive around with the hood-up on sunny days. Not an upgrade in my book
