Experts and BTDT pundits;
I need some help with a good friends car. He gave the 98 A4 2.8 auto to his son and per usual it is now acting up. For some reason, it seems Audis don't respond well to new masters. The car acts like it vapor locks when he refuels, and occasionally starts hard cold as well.
The codes I pulled from it this morning are as follows:

               Address 01: Engine       Labels: 078-907-551-AHA.lbl
Control Module Part Number: 4D0 907 551 AH
 Component and/or Version: 2.8L V6/5V  MOTR AT D01
          Software Coding: 06251
           Work Shop Code: WSC 06325
                     VCID: 6CDCC98A360D
5 Faults Found:

18010 - Power Supply Terminal 30: Voltage too Low
       P1602 - 35-10 -  -  - Intermittent
17546 - Fuel Trim: Bank 2 (Add): System too Lean
       P1138 - 35-00 -  -
17544 - Fuel Trim: Bank 1 (Add): System too Lean
       P1136 - 35-00 -  -
16839 - EVAP System: Large Leak Detected
       P0455 - 35-00 -  -
16825 - EVAP Emission Control Sys: Incorrect Flow
       P0441 - 35-00 -  -

So where should I start rebuilding/replacing - or what is my next step?
TIA

FWIW the boy is a current brain cancer survivor, and I really want to help him out.
