Was just out shooting for 5mins. I come back, and there is droplets of water all over my cam. I even was using an umbrella! What can I do to prevent this in the future? Is this harmful?

ziplock bag. Also be careful bringing it back inside, condensation can eff up the camera. Turn it off and wrap it in a plastic bag before bringing it back inside. Leave it wrapped up until it is not cold to the touch.
If you have a 7D get L-class lenses to seal up the camera better. Otherwise, pull the battery for a while. I would take it that step further than just leaving it off. Condensation in the glass is worse than what your camera would probably have to deal with, they tend to handle light droplets pretty well.

Ok, so when I go out next I
1. Put cam in Ziplock bag
2. Go outside
3. Under cover, remove ziplock bag. Replace with plastic shopping bag and wrap over entire cam
4. Once inside for 5-10mins in the heat, remove
Is this correct?
I really don't get the ziplock bag thing. Doesn't that mean that the condensation already on the cam will evaporate and build up on the interior of the bag, causing it to get the cam wet?
BTW, I have the T2i with 18-55mm kit.

Water + electronics never a good thing. Cameras today include lots of electronics.
Outside in rain - use a rainhood - a good rainhood.
Coming back inside - beware condensation.
Condensation occurs when a cold object (camera) encounters warmer air. Warmer the air - the more moisture it can hold (relative humidity). Warm air contacting cold object is cooled, decreasing the amount of moisture it can carry until relative humidity exceeds 100% and excess water condenses on cold object (even its internal parts). Sometimes referred to as "dew". Think of your bathroom mirror as an example.
Solution - seal cold object in airtight pouch (ziplock) BEFORE entering warm environment. Keep sealed until object reaches warmer temperature. Air sealed in with object becomes "drier" as it warms and its water carrying capacity increases. As long as moisture laden air doesn't touch object while still cold - no "dew".
If your camera gets wet. Immediately remove batteries. (Don't forget the internal one that keeps the date/time). Say prayer to god tron or other favorite deity. Allow to dry completely before reinstalling.

The 7D also has a bit of weather sealing, where the T2i doesn't...
But like Moojangles and Pixelated said, put the camera in a seal-able bag before going inside, and then after the camera has warmed up (usually an hour or more--mine is still cold approximately 1.5 hours later) you can take it out. Remove the card before if you are wanting to use it a little sooner (put it in another bag, as it's smaller and will warm up quicker).
