Step and stepAIC

I???m using "step" and "stepAIC" for stepwise regression. After each step, 
I would like to make an additional calculation based on the independent
variables that have been selected until this step and
their corresponding weights. Where do I have to add this calculation?

dropTerm is the toolbox function stepAIC uses; you could use it to build 
your own stepAIC version.

But also make sure you have read

and consider some lasso variant method instead (this partly 
answers your second question).
