You should be able to intonate that , there seems to be a bit of adjustment left on your saddles. Having said that, ideally the bridge should have been mounted a couple of mm further forward.
I'd grab an Ash body from Stewmac if I were you, their freight rates & delivery times to Australia are excellent. You will have no issues with customs.

OK, without a spraygun you will have to buy aerosol cans pre-tinted. You could try ReRanch - Something like THIS might do the trick and then clear over the top.
To me it looks like you are spraying a solid colour which is not going to work. You need to tint your clearcoat with a liquid stain such as THIS then clear over the top.
From the examples you provided, a red mahogany should do the trick nicely. It will provide a transparent color-tinted look...
