Ive looked into recycling the ABS plastic shells on the CRTs and it seems that you would need several hundred pounds in order to make a transaction, which you seem to have the capacity to do.

As for the glass lead tubes, there is an ewaste recycling company out here that is investing in a machine that separates the glass from the lead. They charge to dispose of them and then they recycle the lead and the glass, that sounds like a good deal for them.

Here is a video that shows the traditional process of recycling crts including the separating the funnel tube glass from the front glass.
