Easy. Easier if you leave the tyre in the sun for a bit to get warm. Should take 5-10 minutes depending on motivation.
I use the local service station compressor (not a ****ty digital one), and a tie down or bicycle tube to help seat the bead.
Depends how much you want to spend...

I stick pretty close. Bought an hour meter from ebay for 3.5gbp. Just saw they come in red so might buy a new one
I use whatever 10w40 is cheap. Bike seems to be happy and quiet with australian brand Nulon but have used plenty of other brands.
I buy these filters from ebay in groups of 10 or 25; whichever works out cheaper.
Ossas ran ajp masters the same as pretty much every other manufacturer. I slide the masters in and have clutch and brake adjusted to start take up right out. No need for them to come near my fingers, and makes the controls feel sharper to me. Also, run my levers flat. Looks like yours are angled down a lot which makes it easier to roll your wrists forward when landing the front wheel on objects or drop offs.
They're in a bunch of chain shops here (Office Works, Coles, Chemist Warehouse, Woolworths, Dick Smiths, Battery World lol). Around 3 or 4aud. Much cheaper than most 9v here.
I say get it because it's good condition, good price, and could be waiting months.
Put the slow throttle tube on it and if things go wrong pull in the clutch.
