If you want some really quick fixes for e.g. leaky windows, I've got solutions that work and can be built by semi-skilled labor in an afternoon.  I developed them for myself, and the extra heat retention and elimination of drafts is just amazing.  You can get everything from Home Depot.

In the long term, you are probably going to want to get really serious with insulation everywhere.

Care to pass them on to me (us)?

It sounds exactly what I have been looking for?

My e-mail addy is on my homepage.  If you're near me I can even show you my prototypes.
