So if you have a shield resist of 25% and a second one of 25%, they will give 1  (1.25) * (1.25) = 1  .75^2 = 43.75%. (A resist of x% corresponds to a damage reduction factor of 1x/100).
The damage reduction factor from shield power is calculated as (1  shield power * 0.0028).
To read the combat log entries, you have to understand the structure. Each line contains two numbers and each shot against shields will give two lines (one for shield damage, the other one for hull damage).
The values in these two lines are:
Shield damage: x (y) with
x = base damage * (1  shield power * 0.0028) * (product of other shield reductions) * 0.9
y = base damage * (1  hull resist) * 0.9 (with 0.95 instead of 0.9 in case of resilient shields)
x is the net damage done to the shields. y is the avoided hull damage.
Hull damage: x (y) with
x = base damage * (1  hull resist) * 0.1 (with .05 instead of .1 in case of resilient shields)
y = base damage
