Problem with AppleID/Authorizing music/prompting me for an old ID no longer in use

Question

I have a 2009 Macbook Pro with a 3.06ghz Intel Core 2 Duo, 8gb of 1067 Mhz Ram, 320gb 7200 rpm HD running 10.8.2, and an iPhone 4S running 5.1.1.
My issues began last year when I upgraded to the 4S. This was the beginning of iCloud, and the beginning of my nightmare. My phone constantly asked me for AppleID's that didn't belong to me and when I hit cancel, they just kept popping up. When I finally got it to my own AppleID, iCloud never fully worked and ended up screwing up all my contacts and deleting many of them until I finally turned off iCloud in favor of syncing with my computer locally. At the time I was running 10.6.8 on my mac, so I assumed it had something to do with the difference in IOS 5 (which was new) and the pre-Lion software on the computer. I waited to upgrade my mac until Mountain Lion came out recently. I did a clean install, and also did a clean install of 5.1.1 on my iphone to eliminate any issues with compatability (pre ios6). However, the problems continued. My contacts continued to have problems until I had to delete them all off my mac and just use icloud. My emails didn't sync (and still won't). My notes don't always sync. Contacts get deleted and music will no longer sync certain songs.
After dealing with this problem for quite some time, I've exausted all sources of help except the forum. I went to the Apple store, not expecting any help and they didn't suprise me there—the geniuses have been dumbed down since the 00's and the floor people only know new products because they're all hipster fanboys. I called AppleCare. No help there either because 'AppleID's are handled separately' and there's no number you can contact them on. So I emailed iTunes. They came back with the same crap everyone else told me: Deauthorize, then reauthroize the computer. Do they really think that isn't the first thing I tried? I also checked the forum here but couldn't find a similar issue. So, like most issues I have with Apple products today, I resorted to my own knowledge and ability to try and figure it out. I tried this method: https://discussions.apple.com/thread/3927039?start=15&tstart=0, but when I deleted the song like it said, I was not able to redownload it. iTunes claimed I never purchased it even though my ID is listed on the song when I hit 'command I' on the song or try to play it.
Basically, iTunes thinks I have multiple ID's. When I was in 4th grade, I made the ID 'raiscool14...', then changed it later to 'reecardoesbueno...', and now to 'r.arnett91...'. I never had problems authorizing my music in the past though, because to my knowledge, each time I changed my ID it overwrote the old one. Apparantly not, because now songs I originally purchased with those older names are asking me for my apple ID and won't let me play them with my current one even though I changed it on the Apple Site. This is what I believe is the heart of the issue causing me the headache with iCloud. When I hit certain songs (about 300/3000), they won't play because they say they were purchase with "reecardoesbueno" or "raiscool14", even though, they should be working under my current ID. And most of the songs do work! So I believe the issue is with Apple, and maybe even with certain special iTunes songs. I noticed many of the "free iTunes song of the week" won't play. I also noted that when you download such songs and try to "complete the album" on the iTunes store, it doesn't recognize that song as being purchased which would indicate to me that it's entered differently in their system, which makes me think that this may also play a factor in my issues.
Also, another issue I had last year (which I don't know if it is related because I can't call iTunes), is that my iTunes account would randomly lock itself out, and then it would force me to change my password. This happened at least 6 times in a 3 month period last year while I was at school. No idea why. I emailed Apple and called AppleCare but they gave me no answer.
Anyways, if anyone can help me with this, please do. I've been an Apple customer since they had iBook's—it's all I've ever known and generally I've been very happy with the quality and service, but I can tell you the way this company has been treating customers for the last 5-10 years is atrocious. The service is, and continues to decline. I remember a time when you didn't even need a genius bar appointment, and the floor people would often try to help you on the spot! Now they're all tied up in beurocratic bulls**t... so annoying when you know that they can do so much better. This company used to be sustained by the customers and it's frustrating to see them turn their backs on the people that were so fervent to keep them going in the past now that they've made a fortune off of us.
