I take it that these are the only 2 problems you have? Any other electronical problems(power windows, low battery voltage, ect). Let's assume that the problems are non-related. If you look at the fuse box it should tell you what fuse goes to what system - this might be the problem with your CD player. You can take out the fuse and see if it is broken.
As far as overheating goes: check the thermostat again.
1. Thermostats can be damaged by severe overheating and you need to be sure it is opening. To check the thermostat: start your car and feel the upper radiator hose. The hose should not feel uncomfortably hot until the engine has warmed-up which opens the thermostat. If the hose does not get hot, the thermostat is not opening.
2. I suspect your radiator may be clogged since you said it is full of rust. Rust can block air flow through the core and reduce the radiator's ability to dissipate heat.
Mechanics use an infrared thermometer to check the radiator. If clogged, the radiator should be removed for cleaning or replaced. Flushing the radiator and using chemical cleaners can remove rust and hard water scale, but may not do much to fix a clogged radiator.
3. Fan - I take it your cooling fan is turning on. Right?
If not, may be a faulty thermoswitch
Hope this helps.
