The scouts would be better with a ML. I would combat squad them to hide them better.
That many plasmas in a squad is asking to get hot! If you want plasmas go with las/plas razorback instead of rhino. You can combat squad that group and leave the plasma cannon for cover fire.
I have not used preds yet but most people prefer auto las to tri las.
I have not been impressed with chaplains much so I would look at changing to a Libby.
With 193 points you could field 2 MM/HF speeders and a MM speeder or just run 2 and use the extra points for upgrades like pw for your tac squads.
