Well thanks to suport from this forum I have finished moving my site from mt to wp along with a complete new design. Its all custom coded php including some of my own DB queries etc. (mainlly as an exercise in learning php and revising SQL). Either way its up and running and opinions would be welcome.
NOTE: I know there are some rendering bugs on Safarai due to a problem in the underlying html renderer (this is a known Safarai bug with colapsing table borders).
Its going to be a git when the next version of WP comes out but thats the price we (I) pay.
