BMW E46 Rough Idle hesitation

Hey I have a 2004 BMW 330ci .
Recently I realized my vehicle has been having rough idle and hesitation. Took it to the shop and they replaced the plugs , fuel filter and maf sensor . They also smoked the vehicle and it has no vacuum leaks on it . It has 110,000 miles . A chrck engine light came on a while back and here's the data from it .

P0420
P0430
P2227

Freeze data

Shrt fuel trim 1= 0.8%

Long fuel trim 1 = 8.6%

Short fuel trim 2 = -0.8%

Long fuel trim 2 = 7.8%

Maf lb/min =2.548

Spark advance = 28

Rpm =2269

Speed =62 mph

Keep in mind the o2 sensors have not been changed and the disa is original .

The first 2 codes indicate issues with the cats. The other code comes back as having to do with "baro"?

What's the maintenance history of the car? How has it been driven, mainly city miles? The pre-cat O2 sensors should be replaced. They're good for about 100k miles.
