Yup, the Warspears really need the
UA.
Legion does ranged very well.
Typically you'll see a pair of Ravagores, a Naga, and then a couple melee heavies(Angelii, Carnivean, or Scythean. The Angelius and Carnivean also have ranged attacks too.)
Then you'll have a pair of Shepherds and 1-2 Forsaken for Fury management.
Plus you'll have the obligatory Shredder(or 2) purely to hand out Tenacity.
You should magnetize all your heavy kits so you can swap between beasts on the same body. Its very efficient and easy.
If you want to start banging out lists, this site is pretty good.

With your choices, here is a basic 50 point list I made up on Forward Kommander.

Shepherd
2 Spell Martyrs
The Shepherds help manage your Fury, you will be running very hot but they can basically keep 2 of your beasts clear of Fury so Lilyth only has to manage the other 3.
The Spell Martyrs are for Lilyth to cast Pincushion from a safe distance. its a great spell if you can tag a key enemy model with it and light it up, but you are exposing Lilyth to do it. The Martyr alleviates that problem.
