Hi Aiden,
The case you describe looks OK and is probably the best you could hope for.
You in full time employment
Your wife with Firm job offer.
Accommodation sorted.
There's not much more you can do other than just make sure your numbers add up and that the ECO cannot find good reason to refuse. As long as the numbers add up you will be OK
It's a much better plan now, and you know just what you need to accomplish.
Keep reading the forum for ideas on potential improvements to the plan.
Good luck mate.
