Without wishing to dampen your enthusiasism to tour, and I know ABZ is expensive, but for a first visit up North it's probably worth going somewhere with a nice tarmac, given the added stress that flying to a new destination as an inexperienced aviator brings.
The weather in the Grampians can be very different to forecast and can change very quickly so keep your options open. On a nice day, the scenery is stunning. If you end up scud dodging it can be most unpleasant.
You can get a FIS frm Leuchars than pick up ABZ approach. If the muck does come in a bit, sticking to the East coast let's you drop down to maintain VFR. You can then turn back to Dundee / Perth if need be.
