FT-quick number crunching needed

I am building a HH style ships, and am using MT missiles as primary
weapons, 
with c mode pulsars for the close range laser weapons, and scattergun
pack 
for countermissiles with a 50/50 intercept rate (modified up/down for
how 
advanced the tech of the relative navies).

I am after some input for the grasers, and using plalon layered armour
for 
the larger ships, require a heavy armour piercing weapon along the lines
of 
k guns, but with only a 12 mu range.

These weapons would need to have a 2 arc version, and a 1 arc vesion (to

represent broadside and chaisers), with the 1 arc being more powerful.
Also, 
the weapons would need to have pds ability.

I was thinking along the lines of using mkp`s, with unlimited fire, and
pds 
the same as a b1 (ie-5 or 6). And havig heaveir versions inflicting
heavier 
dammage. Also using mkp to hit rolls. Size is Small, Medium, Heavy and 
Large.

2 ARC

CLASS	 MASS	  COST	   DAMMAGE
S	      1 	    5		  3
M	     2		   8		 4
H	     4		   13		 5
L	     6		   22		 7

1 ARC

S	    1		   4		 3
M	    2		   9		 5
H	    5		   18		 6
L	    7		    25		 8

These are just very rough ideas, with the numbers picked out of the air.
If 
a number cruncher out there can run these numbers for me (I`m useless at

this at the moment, HELP), I would be able to chose some better numbers
for 
mass/cost/dammage ratio. Also note the larger weapons are very powerful,
and 
will go through armour like butter, which is the idea.
