The alternator belt can be changed from the top, the ps belt is best done from the bottom with the tire removed.
The alternator should have an adjusting bolt and the ps has an adjusting bracket. You loosen the bolts for the alternator and ps pump then use the adjusting bolts to tighten the new belts.

BEFORE ADJUSTING THE ALTERNATOR BELT DISCONNECT THE NEGATIVE BATTERY CABLE OR YOU MIGHT BLOW AN EXPENSIVE HIDDEN FUSE.
I would replace the steering pump belt at the same time you do the alternator belt (buy both).
To take off the alternator belt . First , take off the negative battery cable so you do not blow an expensive fuse on the positive battery cable clamp(or a block fuse under the hood). Facing the back of the automobile , reach UNDER the alternator and loosen the bolt on the bottom right side, now loosen the bolt on the adjuster block on top, you can now turn the adjuster bolt and move the alternator to change the belt.
To take off the steering pump belt on the front of the motor, you need to loosen the nut on the back side of the pulley (right side of pump mount), the nut holds the adjuster pulley in place . With the adjuster pulley nut loose , you can use the adjuster bolt to move the pulley to adjust/take off the steering pump belt.

You are right about removing the motor mount. You have to support the engine with a jack. Use a piece of plywood between the jack and the oil pan. Remove the motor mount and you should be able to lift the engine up about 2-3 inches with the jack. Remove the serpentine belt and then you should have enough room to remove the alternator.
