SOURCE: owners manual for a shimano bicycle
Not sure you will find an owners manual but I highly recommend the book Zinn and the art of bicycle repair. Zinn is the author. He covers every fix imaginable for new and older/vintage bikes. He probably has several versions of the book out.
SOURCE: swapping handlebars across bikes
Wouldn't it have been easier and cheaper to get the gears replaced on your old bike?
There really isn't enough information here to answer your questions. There are so many variables between the old and new bikes:
Drivetrains compatible?
Handlebar diameters equal?
Stems compatible? (maybe swap the whole cockpit, brakes, shifters and all)
Don't take this the wrong way, but if you don't understand these questions or their implications, maybe you should take your old bike and the new one down to a real Bike Shop and let a mechanic see what it is you have to work with and offer suggestions.
Testimonial: "Thankyou very much for your feedback, I must admit I didn't understand the complexity of the procedure. I have now resolved the issue"

You don't mention which shifter(s) malfunction or if you're even pedaling the bike while shifting (I make NO assumptions).
If you operate the inner shift lever (NOT the brake lever) on each side through several clicks that should RELAX any tension in the shifter cables. Then if you pick the bike up and pedal it forward a couple of turns the front shifter should drop the chain the the lowest chainring and the rear derailleur should shift out the the smallest cog.
With the bike suspended (say, hanging from a low tree branch by the tip of the seat) you should be able to turn the cranks and manually pull sideways on either exposed shifter cable where it runs down along the downtube then release it.
This should cycle each respective derailleur through its entire range. If the cables don't travel sufficiently in this manner, the shifters will never make them do it either.
Perhaps you could CALL the Bike Shop and they would talk you through a quick operational check.

If it is when you pedal, check the bottom bracket (where the cranks are attached) The bearings might need changing which would cause the noise.
Do the handlebars rock back and forward, if so, check and tightent the headset, check the bearings inside if they are dry or broken, replace and re-grease.

Manuals for components won't teach you how to actually USE anything.
Search engines will answer specific questions, usually with videos.
Shifting, braking, fixing, just about anything.
