Nicely done!
The starter set is by far the best value for money per figure.
When you get around to your Stormcast, remember, they don't have to be gold. They don't even have to be silver, although the silver and gold look awesome.
The turquoise Stormcast, IMHO, are some fantastic looking minis. So leave your options open. Google about and see what others have done and you can even check out the GW web store for alternative paint schemes, before you decide on which to go for.
