Is there a cap for armor penetration and magic penetration?
The highest magic penetration I have ever got to was 45%. Is there a capped armor/magic penetration?

No, there's no coded limit on pen. Whatever you can get from items, runes etc will stack.
There is no brakes on the penetration station

Meddler !
Only as much as you can buy or use runes/masteries/abilities for.
What is armor penetration?
lethality?
Lethality is just flat armour pen.
Technically, it's 40% Lethality that's converted to Flat Armor Pen, and the other 60% scales off with the enemy target champion's level.
There we go.
There is no actual cap, but there is a limit to how many items/runes/masteries you can get.
So...
70% Armor pen, and black cleaver...
heh
