Hey mate, welcome aboard.
Where abouts in QLD are you from?
Workout:
I would give this a read and pinch a workout from one of these guys:

There's some good stuff in there, definitely worth taking 5 min to read them.
Diet:
I know you said you don't want to go all out with it, but I'd suggest having a look at one of the 'all out' diets just to get a feel for things.
Will make it easier to grasp how much food you should or shouldn't be eating.
There are a bunch of premade diets on here for different calorie intakes. 2200, 2600 or 2800, 3200 and 4000 I think.
Once you know much much you should be eating you can check out a premade one to get a feel for what an all out version is, then you can modify it to suit you better.
There's a few formulas around you can use to figure out how much you should be eating if you feel like doing some poking around.
There's some here:

But if you can't be bothered and want the easiest ball park formula I've seen...
To lose fat: 12-13 cal / lb of bodyweight.
To maintain: 15-16 cal / lb of bodyweight.
To gain: 18-20 cal / lb of bodyweight.
Oh, I hear that hydroxy products are a bit of a sham. I'd just stick with something simple.
Check this out for ideas if you haven't seen it yet:

Anyway, hope some of that is useful. I don't like to reinvent the wheel, so if someone has done the hardwork already, no point doing it again
