Evap is inside cabin area , condenser is outside infront of rad and behind intercooler (Normally ) ..
Line length is not crucial , but size is within reason , changing a few feet / meter wont make any difference in the length to size.
If you were to add 10 meters , then as in wiring rules longer distance needs larger dia of wire , due to voltage drops , And in gases , volume decreases with longer lenghts, so the pipe / tube needs to be larger for a longer distance.
BUT a small increase in length will be just fine, it will need a more gas though ,small amount of extra gas to fill the increased area, very little , say a few more gramms to take up the extra space.
New hoses that are just for AC and have internal lining are the best..Plus it is always good to keep the hoses bent smoothly for less restriction in flow..
