I will be the first to admit that I am purposefully looking for 'negative' verses in these texts you mention, from a position of relative ignorance. I don't know all that much about Islam, but I'd imagine like most religions it's a hodgepodge of notions, good, bad, sensible, and incoherent.
Cherry-picking? Yes, but that's sort of what you were asking for.
Incorrect translations? To be sure, I'd have no way to tell, but I'm perusing sites now, where the articles seem to be written by Muslims/ex-Muslims, who seem to know their stuff.

Stoning a women to death for adultery? That's horrid, isn't it?
Why does she need permission?

Are Muslims allowed to be friends with me?:
http://www.islam-watch.org/Kammuna/Beating-Women-Sanctioned-By-Allah-Prophet.htm:
Is this true? The article makes a perfectly sensible case that it is.

Anyhow, as to be expected from ancient writings, written by uneducated people (all religious texts, for the most part), mixed up, and mashed up over the centuries, it's a mixed bag, and as is patently obvious, is interpreted in a manner that most pleases the reader.
And far too often these readers are dangerous maniacs (not in itself the fault of any one religion, but if the writing is unclear enough so that the dangerous folk can twist it to their will, I am forced to question the divine nature of any holy text).
