What to get next?

[Beastlord]

Planning some reinforcements for my Delgon.. I currently have:-

2 Acolytes
2 KalJoran
2 Soldiers
4 KalDuru
1 KalJoran
1 KalGush

I really fancy more KalJoran as i love the idea of a proper shield wall, but I probably need more soldiers too. What i'm mostly wondering is should I get a priest? Haven't quite worked out the chain of command but would he be essential as my force grows? Bodygaurds?

Any musings anyone has on the workings of the Delgon in game would be great

I would definitely recommend you get more soldiers as they are the bedrock of the force. You can get by without a priest (using the acolyte as a NuraKira), but at some point he'll be very useful and most scenarios use him. The bodyguards are also rather handy and nice fighters.
Once you have a priest and his bodyguards you have a force that activates as a single block very effectively. You can also use the priest as NuraSen Gohral.

Hmmm, more soldiers, KalJoran, and a Priest with bodygaurds then... Cheers!
Probably stupid question: Is there any reason why you would use a NaruKira over a NaruLehn, other than the bodygaurd? Does the fact that he is Elite have much of an effect? (I'm very slow in the brain)

Hopefully answered already! You would only use a NuraKira if you had chosen a small expeditionary force without a priest to lead it.
