If i get the extra effect perk which lets you put two enchantments on an item, will i be able to enchant the already enchanted ghostblade. (It already comes enchanted, ignoring 3 points of armor i think.)

You can't put new enchantments on already enchanted items, but I'm not sure if the Ghostblade counts as having a prior enchantment? Does it have a charge? Or is it like

hmm

Thats exactly what i thought when i got it, but now that you mention it, i cant even place a single enchantment on it. Darn it, i wouldve loved to put an ice enchantment on it, cus it kinda fits the swords name. On top of that, it wouldnt be such a weak sword. Kinda like id did with Wuuthrad the Devourer. Absorbs 15 points of health. Currently my strongest two hander.

I know you can't disenchant it but putting more on it...

Its probably like the Wuuthrad so its possible.
