I've got a good amount of experience with OME, and I'm very satisfied with the lift. I'm running 934 front springs and 949 rear springs, which is what you should have ordered for your LJ.
OME springs are side specific. make sure you've got the taller front spring on the drivers side. each spring should have been marked A or B. In front, A goes in the drivers side. in the rear, A goes in the passenger side rear. This combats twisting due to engine torque.
if you've only had the springs on a couple days, you need to wait at least 2000 miles for the springs to settle. mine took around that long to settle completely.
with OME springs & shocks, keep in mind you need at least 1.3" rear bumpstop extensions in the rear, the OME included 0.8" is NOT enough. also, without a 1.25" BL, if you do not have those 1.3" bumpstop extensions, the rear track bar relocation bracket will hit the underside of the tub. aftermarket rear track bars can also cause issues. here's a write up about all that.
now, the reason the front axle is off-center is due to the track bar. DO NOT BUY AN ADJUSTABLE FRONT TRACK BAR. The new front track bar WILL hit the diff cover, there is no aftermarket front track bar that fits with less than 2" of bumpstop extensions in front. Here's a write up documenting track bar vs diff cover issues on 0-3.5" of lift.
Keep the stock front track bar, wait for the suspension to settle, and then drill a new hole for the axle side if it's even noticable. I doubt it will be very noticable by the time those medium duty springs settle on the heavier front end of the LJ.
now, that brings me to the next point - you said the front is too low. thats because you bought the wrong springs for the LJ. the LJ is heavier in the front and needs at least the heavy duty 933 springs, assuming you have zero extra weight on the front end. You should have bought 933 or 934 springs. The 934's are OME's ZJ V8 lift springs and compensate for the inherently front end of the LJ. To level out the front end, I'd suggest buying the 933 or 934 springs, depending how much weight you intend to put on the front end....for example, aftermarket bumpers or a winch, get the 934s. Here's a write up on choosing a spring rate for your Jeep.
i've documented all the technical info around what i've explained in my build thread - Unlimited04's LJ Build - JeepForum.com
Read that over before buying stuff to try to fix issues you don't have.
