As i am simply a formula junkie and not a mathmatician (i am actually failing my maths at school, though i am getting A's & B's in all my other subjects... go figure :\) Would it be possible for somone / many people to give the following formulae:
1) A Formula that displays how many resources of attacker it takes to kill 1 resource of defender using conventional weapons.

Let
wts be the weapon targeting speed of the attacking unit.
Let
agility be the agility of the defending unit.
Let
armor be the defending unit's armor.
Let
power be the gun power of the attacking unit.
Let
hitprob be the probability of an attacking shot hitting the defending unit.
Let
hts2kll be the number of successful shots required to kill the defending unit (on average).
Let
shts2kl be the total number of shots (counting hits and misses) to kill the defending unit (on average).
Let
ships be the total number of ships required to kill the defending unit (on average).
Code:
hitprob = (25.0 + wts - agility) / 100.0
hts2kll = ceil(armor / power)
shts2kl = ceil(hts2kll / hitprob);
ships = shts2kl / guns;
Note: the ceil function takes the ceiling of a number; that is, the smallest integer greater than or equal to the number.
This gives you how many attacking ship(s) to kill 1 defending ship, on average (
e.g., 1.75 attacking ships to kill 1 defending ship).
From there, you can calculate costs. If you want the cost to kill 1 ship, then multiply
ships by their cost (
e.g., 1.75 ships times 4000 resources yields 7000 resources per kill). If you want to normalize by resources, then divide that by the cost of the defending ship (
e.g., if each defending ship costs 2000 resources then 7000/2000 = 3.5 attacking resources required to kill 1 defending resource).

I presume you mean freeze? EMP is much easier:
Let
empr be the EMP resistance of the defending ship.
Let
guns be the number of EMP guns on the attacking ship.
Code:
ships = (100.0 / (100.0 - empr)) / guns
This gives you the number of ships to freeze 1 defending ship, on average (typically, this will be less than 1--
e.g., 0.4 ships needed to freeze 1 ship). From there, proceed as above.
You can see some coded examples (in C) in my unit table generator:
