On your rune suggestions, you have things backwards. For mix of AD and AS, you want AS on your Quints and AD on your Marks.

The Mark/Seal/Glyph to Quintessence ratio is different for each rune type. For attack speed, Quints are one of the biggest bangs for your buck. Each AS Quint is 2.65x the potency of an AS Mark, when normally the ratio is around 2x to 2.3x or so. This is why a lot of high level players take 2 attack speed Quints on their rune pages.
