Thats alot of points gone into your WS, in such a small game i dont think you will need the BL. Change these for TLSL, you get more shots and they are re-rollable =win against most transports. Next lose the rangers and get some more DA with exarch and Blade storm. The sheer volume of fire power you will put out should be enough to hold up anything the enemy throws at you.
Based on the campainge rules here is what I would take:
10x DA w/Exarch, dual shuriken catapult, Blade storm -152
WS w/TLSC, Spirit stones -110
10x Guardians w/SL heavy platform -95
3x War walkers w/x2 SL -135
Total -492
The Guardians will be the objective holders while the DA advance and take out the enemy transports, the War walkers will be able to swing around and hit the enemy in the flank. If you dont want to use the WW you could drop them and get a Wraith lord with x2 EML which would come in at 140pts. This will give you another TL weapon to throw at the enemy, also giving you a choice of shot. Krak to pop transports followed by Plasma to kill the juicyness inside.
Hope that was of some help to you good luck in the coming campaigne.
