help~error codes

I got three error codes in my 2000 Mazda 626. P0421, P2242 and P0000. I checked the OBD II codes. It says P2242 O2 Sensor Positive Current Circuit High (Bank 2 Sensor 1)P0421 Warm Up Catalyst Efficiency Below Threshold (Bank 1)
Anybody know what that means? Do I need to go to the garage? Thanks!
