Narrative:

Chain of events: while pushing back from gate at frankfurt, germany, our captain was having difficulty hearing the tug driver due to bleed through from the cabin PA into his headset despite PA not being selected on his communication panel. This situation continued during taxi out on ground control frequency. Initial taxi instructions to runway 7L were via 'north-H-a.' approaching taxiway north, the captain noticed a conflict and elected to bypass taxiway north to avoid. Before we could notify ground, new instructions were given to proceed to taxiway left for runway 7L via 'a-G-north-H-a.' approaching taxiway left, the markings for taxiway left and taxiway a were confusing and the hold point was inadvertently missed. At this time tower issued new instructions to runway 7R via 'west/right.' while crossing in front of runway 7L instructions were given to 'expedite taxi' due to an aircraft on 4 mi final. In our haste to clear the approach end while entering unfamiliar areas, taxiway right was accidentally bypassed. We were then redirected to runway 7R via taxiway c-r. Remainder of taxi was uneventful. Human performance: taxiing on the fra ramp is very confusing due to the numerous faded ramp markings, multiple signs, radio congestion and foreign controllers. Also, the entire flight crew was somewhat fatigued due to poor/no air conditioning at the layover hotel.
