Hey, you, I/L Mage. Yeah you.

Apparently not.

haha oh wow.

From what I've been told, Elemental Wands and Staves is like having another Amp. Though no one has confirmed this, I have seen two different formulas in the past. No idea which one it really is, but

(Elemental_Amplification% + Elemental_Weapon% -100)
or
(Elemental_Amplification%)*(Elemental_Weapon%)

i.e.
140% + 125% - 100
or
1.40 * 1.25

Haven't heard anything about changing MA though. Naturally just assumed it was a Base Attack modifier.
