You shouldn't need to replace the plug boots unless they are damaged or the wires are bad.
To replace the plugs, start at one end of the engine, pull up on the plug wire boot to remove it from the plug, then use a spark plug socket and extension to remove the plug. Examine the plug for any problems. Now check the gap on the new plug, adjust as required (the plug number and gap will be on the emissions sticker under the hood) install it into the head and tighten it down. If the boot is damaged you simply follow that wire back and remove it, select the same sized wire from the new set and install it in reverse of the way you removed it.
