electrons are carried via NADH from glycolysis to oxidative phosphorylation.
I thought that NAD is reduced to NADH during the last step of glycolysis. If NAD is reduced..isn't it giving its electrons to glucose to form the 2 pyruvates (reduction - addition of electrons to another substance)? So if NAD gives its electrons..how can it still carry them to OP?

NAD+ is reduced MEANS it receives electrons... note the passive form.
And reduction in Biological systems don't usually mean whole electrons, usually they come in the forms of hydrogen atoms.

NAD is an electron acceptor (It's counter-intuitive but gaining electrons means you are reduced. Losing electrons is oxidized) These extra electrons that NAD and FAD gain from glucose also allows it to accept hydrogen ions, which are positive.You know oppisite charges attract.
