The sunroof has 4 drain pipes. Two in front, two in back.
One or more of the pipes could be leaking at the joint where the pipe meets the roof. OR it could just be time for a new seal.

If you search, you will find lots of info - including clock repair...I believe there is a resistor (available at RadioShk) that fixes many broken clocks.

Get a new radio, and 3" speakers - the speakers you have in there now, are beyond cheesy - I'm surprised MB had the guts to put them in in the first place. The original radio will only have a L and a R out. Those leads run to the fader switch (behind the gear selector) and from there, go to the (cheesy) paper speakers. Either bypass the fader and re-wire it properly, or use the fader and original wiring - be sure and adjust the fader control on the new radio.

Have fun!
