I've been using Ealge for a little while now, but there are some things that I do (people have told me to do specifically) and I don't know why.
EAGLE is a very powerful tool. I had done CAD (and manual layouts) before using it, but I found the learning curve to be quite steep.

Isolate: Distance between polygon areas and other signals or objects in the Dimension layer (default: 0).
In other words, if you flood a layer to make a ground (or power) plane, this is the distance from the edge to other features (vias or pads, the board outlien, for example).

Hmm. Not sure what you mean or intend. I also find the SMASH command confusing. Are you SMASHing existing parts or ones that you created (in the library editor)? Use SMASH to isolate the >NAME >VALUE text (so that you may move or delete then).

That is called a thermal. It is a break to stop the large plane form robbing heat from the via or pad when it is soldered. You can turn it off (Change -> Thermal -> On|Off). A board with planes and no thermals may be hard to solder.

Change -> Thermal -> Off
