I think no.7 says so...

1. Remove the A/C compressor bottom bolts and loosen the top bolts.
2. Remove the oil level indicator and tube.
3. Raise the vehicle. Refer to Vehicle Lifting.
4. Remove left and right front tire and wheel assemblies.
5. Remove the engine protection shield mounting bolts.
6. Remove the engine protection shield.
7. Remove the steering gear crossmember, front.
8. Remove the left and right wheel drive shaft.
9. Remove the front drive axle clutch fork assembly.
10. Disconnect the prop shaft from the front axle pinion yoke.
11. Remove the oil pan drain plug and drain the oil.
12. Unclip the transmission cooler lines from the engine block.
13. Remove the front differential bolts and set aside the front differential.
14. Remove 4 transmission bell housing bolts that are attached to the oil pan.
15. Remove the remaining oil pan bolts.
16. Place 2 oil pan bolts in the jack screws on the oil pan and tighten evenly to release the oil pan from the engine.
17. Clean and inspect the oil pan.

Motor mounts are going to keep the engine from falling.

Crossmembers like these usually just stiffen the frame up while others do hold things up, like the transmission crossmember. In this case, I wouldn't worry about it, especially since the manual says to remove it.

Oil Pan

No you do not need to take the rack and pinion out to get the oil pan out.
