Espresso is basically just a theme, gives a square bar at the bottom instead of the standard round one.
As for your voicemail problem, go to Menu>Settings>Call>Voicemail settings, and enter your phone number (you might have to select "my carrier" under Voicemail service first).
WiFi tether I have no experience with, no use for it.
I'm sure there's a theme/taskbar out there that'll bring you back to a stock taskbar...I haven't messed with it yet (I agree about the signal icon though)
Had the same problem with the voicemail! Thanks @Tatonka Hero!
