Think that sounds about it to be honest! Not sure if you have ordered the parts yet or not - I ordered mine from Shop4Parts.co.uk, although there are other places (Jamie Porter) springs to mind where the parts are a little less expensive.
Not sure what oil you intend on getting, but as a personal choice I use Selenia 10w/60.
It maybe worth buying 6 of the small inlet tube gaskets as well, as these are prone to leaking, especially if the rear cover is coming off, although I'm sure someone may correct me if this isn't necessary. I only say this as I found two of mine were leaking a few weeks back!
