We just bought a 2001 Dodge Caravan and had the same problem. We went back to the dealership and one of the young guys there discovered it was caused by the luggage carrier bars on top of the van. The two cross bars, when removed, will get rid of the whistling noise. .
It sounds like it may be an exhaust leak, upon aceeleration, more exhaust escapes and makes a louder noice. If out of warrenty, take it to a muffler shop that does custom exhaust work, because a crossover pipe is a crazy cost from a dealer.
To improve a bit on the first answer. The cross bars should have rubber inserts to close the gap in them. If these are missing you'll get the whistle. Yes removing the bars will eliminate the sound.
My 2003 has what I think is your issue, it is alternator whine amplified through the stereo, even when the radio is off you here it. The only time it goes away is when you actually remove the radio. This is caused by a bad alternator. You can help remove the noise with an electrical filter (capacitor to ground).
Air conditioning belt: I had an annoying screeching sound on acceleration which turned out to be the a/C compressor belt which I replaced for $10. It started making the noise again so I tightened the belt and it went away. You can test to see if this is your problem by turining the A/C or defrost off when the sound comes.
I have noticed this on my '03 Grand Caravan, and have found it to be the fuel pump. I really notice it when it is hot outside. The dealer said they wouldn't touch it until it goes out. They have replaced them and the new ones will start to do this sometimes. If the dealership told me to wait, I will. They are usually known to try and take all the money they can from you.
Sounds like you have two separate problems, on acceleration the transmission could be slipping, check the fluid level and have a mechanic look at it. During braking, it is most likely warped rotors, which will need to be replaced to stop the shuddering. As long as the pads and shoes are in good repair, the shuddering during braking will not harm anything aside from it being annoying. The transmission can suffer serious irreplaceable damage if it is not checked out immediately.
