If you are removing lams, I'd basically ignore the GLB's contribution since the good wood on the lower fibers are gone.
Are you using an unbraced length = to the span for the channel? If you are bolting to the existing GLB or connecting to the diaphragm somehow, you can reduce that for LTB. What about a W8 or W10? Shore joists/rafters, remove (E) header, put in new PSL, Powerbeam, or Steel flush beam?
Exactly. Those are "filler" layers, and are generally low-grade. Reality is, you don't know what they are.RE: loading, with the proper number of connectors, you can ensure that they will be loaded "simultaneously", but you still won't know what the wood contribution is.
