Vaccuum lines? Leave them open?
I have a short ram intake on my 96 ek hatch and noticed while looking under the hood there are two open vaccuum lines without hoses attached them. On of the lines goes to the throttle body and the other somewhere else. I assume that these were previously hooked up to the stock airbox and am just curious to know if I should seal them or plug them. Could it possibly be hindering performance? They seem to make a whistling sound when the engine is on, so i'm not too sure. Any ideas?

just seal them shut with some JB Weld, you don't need them... and disconnect your throttle cable while you're at it, you don't need that either... 
Everything in an engine compartment is there for a reason!!
they should be connected!!!!

well, sometimes it drops low, then goes back up to like 900rpm or say and stays there. pretty much all the time it idles at like 900rpm and after sitting for like 4-5 mins it drops a little and the car rumbles a bit and then goes back up...
also, sometimes when driving it a little hard when i come to a stop light, it drops real low and then goes up again too and also when i start it, it goes low then jumps to like 2000rpm or so and slowly climbs down as it warms up
any ideas?

Vacuum line for the fuel pressure regulator(FPR)?
FPR is located on the top right hand side of the fuel rail(see above pic), it's a gold/bronze cylindrical piece with a cast aluminum base that bolts to the fuel rail itself. The top FPR port should have constant vacuum from a manifold source.

That double open-ended steel tube is just your OEM breather for your valve cover, nothing to worry about there.
When your intake tube was installed, a yellow hose was attached to both the valve cover and the intake tube taking the place of the steel tube. The only reason that it is still there is that it is permanently attached to your throttle body coolant line(the other metal tube underneath)
The whistling noise your hearing is probably just the velocity of the intake air resonating in the aluminum tube, nothing to do with the metal line you illustrated.
