And I must say the Dremel wall tile cutter is also an awesome tool for the sleeve:

For the crankshaft I use simple grinding stones for a Dremel tool.
For raising the ports you can also try to modify an headshim so it will fit over the sleeve. When placed under the upper edge of the sleeve you will raise all the ports. But what you add to raise the sleeve must be taken away from the head to be sure the combustion chamber will stay at the same height.
This is done a lot, for some brands they are even available:
