IOS 5 Update, wait, re-connect, back-and-forth may solve some things...

Question

I just updated an iPad first generation (iPad 1) and I was going to scream as my Mac Pro iTunes showed no music, videos or photos.
I was luckily surprised to see that my Apps were kept in their own folders. (I have close to 250)
I disconnected the iPad.
Opened the new 'Music' app and it said 'No Music'.
Opened the new 'Videos' app and it said 'No Videos'.
I was very frustrated. I re-connected the iPad to my computer and I saw the music and video playlists in my Mac Pro iTunes. I could play the vidos and music from my desktop computer, but I could not find any in my iPad (iTunes was showing all of it was there, just not the iPad)
As I started to write feedback to Apple and trying to do some screenshots in my iPad, I suddenly saw that some playlists showed up. Then the videos showed up. I would say that it seemed like maybe the iPad and iTunes try to do some checking or sync in the background and suddenly somethings just show up. I am not sure if this is what happens or not.
Currently, many of my songs are missing their album artwork (album covers) in the 'Music' app. I can see these album covers in my desktop iTunes. I know that these songs are from my personal CD's I have ripped or Music I have downloaded from other services. Like I said, the artworks is showing fine in iTunes, and was showing fine previous to the iOS 5 update, so what's wrong?
Let's share more tips, insights and help with the Music artwork, playlists and videos.
p.s. By the way, very annoyed that 'Newsstand' is an App you cannot drop inside a folder or group. iBooks, Messages, Reminders and AirPort Utility can be dropped inside folders/groups, why does Newsstand has to be a top icon?

i have 3 problems listed below while using iphone 4s with ios 5.1 version
1. The screen goes blank(dark screen) when i try to call back (i.e redialing 2-3 times). then i have to press home button and once again i have to press call button(sometimes green layer which will be on top of the screen) and press red button to close the call and try once again.
2. Sometimes my network drop zero then start searching network then display no service for few second and then the network once again appear (no issue with the network provider i checked with other phone which is working fine)
3. When there is incoming call the people on the other end of the call (caller and not me) cant hear for first 2-5 sec (i did a count..ha..ah) they wont be able hear.
