What about having the 6" all on one plane? Disperse the funnels to suit You could probably lop a considerable amount of dead space off either end though that may have the sardine can effect...
I'm thinking about mounting a second 6 inch up there... not sure. But yeah, I have dead space right now. I think I can change that though...

And why do you need AA guns on a ship from 1906?
She has barely any details
And they're not technically AA guns, they are light anti-torpedo boat guns... but they'll get used as AA mounts eventually.

Why design a ship in Springsharp and then draw it out and then decide to make it smaller to cramp it up?
Doesn't make much design sense to me. Design a decent ship in SS first and then draw it. Decide what you want before you draw anything, else you just end up with a horrid mess and folks poking holes in it. Don't forget a larger ship has better seakeeping and will be more stable, a short ship is going to be cramped and wet, probably not much good for cruiser work when the weather gets tough.

Light anti-torpedo boat guns don't have high elevation for AA work. You'd need to change the mount in the future.

It's the way I work with springsharp. I drew the base hull, deciding how long I wanted it. Then I put it into SS and decide other details. I'm more comfortable working that way...
Plus it doesn't matter. I decided to keep it more spacious.

Indeed they don't. Plus the 12 pounder isn't great for AA, so I'm thinking about inter-war refits to mount 2 or 3 pounders (has the 3 pounder been drawn?)

I like the cruiser but I think you have to move around some of the guns. The aft-most 4" guns (just below the 6") will suffer greatly from the blast of the 6" gun above. As mentioned earlier, you can put 2 4" just in front of the forcastle-break sided with the bridge.
You can also add torpedo tubes.
This can give you some inspiration (she was 446ft long overall)

I'm wondering if 1906 might be a little early for oil fuel instead of coal or a mix?

So... I'm not sure what to do next and would like some advice.
Shall I do:
-A secondary WW1 eya flagship, one built for the minor bases (i'll eventually work out the main and minor stations)
OR
-A modern era vessel in use by the company. This one will need more advice and conversation...

Try a 20's-30's design.
