Shimano FH-RM65 Hub

So my rear hub on my 2010 Genesis Core 20 seems to be not sounding and feeling to well. Feels rough and gritty when turned. I will be attempting to service myself after doing some research. I am just not sure what size cone scanners I will need, don't want to buy the wrong size. Can anyone please help.
I have also noticed recently that the cassette has a slight side to side movement. Is the cassette meant to have some minor movement or is this due to the state of my hub?

Usually 13mm front, 15mm rear for cones?

Has the freehub body got play? A little wobble is not unusual.

Thanks Supersonic,
I haven't taken off the cassette yet so at the moment still unable to check the freehub. Still trying to find good deals on all the tools that I will need.

You should be able to get a pair of cone spanners, each with four different sizes, for £6 or £7 on Ebay.
