I agree with Trouble. Google does NOT give IP addresses or locations of customers - of course, in many cases, locations are public, like it's no big secret that I live in Finland. The only one to possibly give information like this would be the Police, and I strongly doubt even they would do that, unless in a process of Court of Law, and that would namely be to your lawyer.
I'd say you're under some sort of an attack. Someone wants you, or someone dislikes you because of something you may have expressed in some Forum. It seems someone may block you from changing your password?
What to do, I don't really know. All I can recommend is a thorough scan.
