Default Serious problems with my 99 a6

Well first off I just bought a 1999 Audi a6 Quattro 2.8 n/a so I don't have the money to take it to a dealership.

It was kinda cofusing the list of obd codes. It was general list of codes so im not sure if they were all right, and for my audi a6. Also some of the codes were the same type of code but the code number was diffrent(you will c)Here are the codes it threw.If some one can confirm my codes are right that would b great.

P1136- long term fuel trim add. Air, bank one system to lean.
P1129- long term fuel trim, bank 2 system to rich.
P1138- long term fuel trim, bank 2 system to rich
P1127- long term fuel trim mult., bank 1 system to rich.
P1391- camshaft pos. sensor, bank 2 short to ground
P1338- camshaft pos. sensor, bank 1 open circuit.
P1519- intake cam shaft- control. Bank 1.
P1522- intake cam shaft control. Bank 2 malfunction.
P1640- internal control module (EEPROM) error
P1141- load calculation cross check range/performance.
P0302- #2 cylinder miss fire
P0301- #1 cylinder misfire
P0411- secondary air injection incorrect up stream flow.
It also threw p0300 and p0322 I can't find these codes anywhere if anyone knows what they are I really need to know.

So from all these codes I don't really know where to start. Are there any a6 gurus that can help me out???

The one that worries me the most is the P1640. I found this link for that error that has a very good explanation:
18048/P1640/005696 - Ross-Tech Wiki

Possible Causes
Engine Control Module modified (e.g. Chip Tuning)
Engine Control Module faulty

Possible Solutions
Contact your Tuner
Replace Engine Control Module

Most of the errors I'd say are probably related to the ECU trouble so personally I would start there.

Also the 2 codes you are looking for:
16706/P0322/000802 - Ross-Tech Wiki
16684/P0300/000768 - Ross-Tech Wiki

Everything relates to miss firing / engine trouble from what you have posted. I hope someone else can jump in and give you some advise since I'm most definitely not a guru
