My 02 cents
First the C 210 was built from 1960 to 1985. The 1985 C210R is a completely different airplane from the 1960 210A. All the weights dimensions and virtually all the systems are different. Therefor you need to know the model and year of the aircraft you will be flying in order to prepare. One very simple example is all C210's built prior to 1974 (I think) have ASI's in Mph while after that they were in knots. So, for example, saying fly the approach at 90 means nothing without specifying the weight of the aircraft and the units.
In any case the fact that you asked about circuit speeds seems to indicate that you are treating this like a club checkout.
If you are going for a proper job on this aircraft than the check pilot is going to tell you what speeds the company wants the aircraft to be flown at. What you should show up with is a good knowledge of the aircraft limitations, systems and checklists, all of which can be done by studying the POH before hand...which I guess is a long winded but more polite way of saying RTFM
