memory address sharing

can these potentially cause problems or is it normal to have so many shared ??

I wouldn't worry about it. If you haven't had crashes by now, it won't cause any issues.

I also have memory addresses shared as well. Common thing.

This is normal. As you can see, it's always the PCI/AGP bus "sharing" a ressource with the device attached to that bus. If they didn't share ressources, your CPU had a hard time accessing those devices.
Windows without access to videocards and soundcards is rather useless, don't you think?
