ok thanks, yea i was able to google the end caps and reducers and find those online, but I couldn't find anything online similar to the screw clamp by googling 'screw clamp' or 'screw fastener.' Is there some other name these might be called by, just so I know better what to ask for? In my experience the people who work at my hardware store in town are usually pretty clueless about anything I might think to ask for, even with the right name! So something I don't know about seems pretty doubtful... Thanks again!
