A clutch pedal that's sticking is a recipe for a burned out throwout bearing, and in a worst case scenario can cause slipping and rapid destruction of the entire clutch. Possible causes: Linkage needs lubrication, binding clutch cable, needle bearings at clutch release shaft on each side of the bellhousing are insufficiently greased, clutch pedal return spring broken or missing. The jake brake problem may have just been the tip of the iceberg. Instead of adjusting the switch, the issue of the clutch pedal not returning should have been addressed.

That's what I said a long time ago :P actually....... what you said was; "clutch switch ok?". at that point in the thread, i would have agreed as well, but there was not yet enough info to say for sure. the brake on/off or position switch could have been bad, the electrical circuits for those switches could be the problem, the ecm might not have been recieving the engine brake request at all... these things and more could have been the problem....... BUT, now that i know the cruise doesn't work, none of those problems i just listed are possible (at least not exclusively), it's more likely to be an interlock problem
