my g/f has a 93 jeep wrangler that has a leek under the windsheild. we suspect its the strip that seperates the window frame to the tub. Would this be what we need to order? http://www.jcwhitney.com/WINDSHIELD-GLASS-SEAL-CLIPS-FOR-JEEP-WRANGLER/GP_2008692_N_111+1993+200004043+600008147_10108.jcw
Also the vent hold water and when she goes to drive off the water floods into the heater and onto the floor? whats up with that?
and dont worry she does know what that extra lever on the floor is for and knows how to use it  

that more likey the drain is plugged not a bad window strip, open the hood look for a hose stickin out on the passenger side fire wall, grab hold and yank. the problem will likey go away.  

I don't think that you need the windshield seal, more likely it's the cowl seal that's leaking (it's pretty common for them to leak).  The good news it that it's much easier to replace - you just lay down the windshield and unscrew it - no need to remove the windshield glass

Here's an example of the windshield cowl.
