Sorry, I never noticed this post, for some reason I did not get an email from Fixya. If it is not too late..........
p0110 is the Intake Air Temp sensor or its wiring connector at fault. This is located at the side of the air cleaner housing.
p0135 is a fault in the No 1 oxygen sensor in bank 1, or its wiring connector. This thing is located in the exhaust manifold under the sheet metal shield at the front of the engine
p0450 is an evaporative emission system pressure sensor fault. Many people recommend replacing the fuel filler cap gasket before going further with this one

p1410 and p1411 indicate an EGR valve malfunction, and it may be enough to simply clean and check it, located on the engine next to the firewall. Also check the vacuum modulator and Vacuum Switch Valve, as shown here p46, 146, 152, 190

No it is not Catalytic Converter related. Your fuel tank pressure sensor must be disconnected or the wiring to it defective for the evaporative emission system.
P0453 HONDA - Fuel Tank Pressure Sensor High Voltagehttp://engine-codes.com/p0453_honda.htmlForum CodePossible causes- Fuel Tank Pressure sensor harness is open or shorted
- Fuel Tank Pressure sensor circuit poor electrical connection
- Fuel Tank Pressure Sensor
- Faulty Engine Control Module (ECM) When is the code detected?A high voltage signal from the fuel tank pressure sensor is sent to Engine Control Module (ECM).
P0450 - Evaporative Emission Control System Pressure Sensor Malfunctionhttp://engine-codes.com/p0450.htmlForum CodePossible causes- Evaporative Emission System (EVAP) Pressure sensor harness is open or shorted
- Evaporative Emission System (EVAP) Pressure sensor circuit poor electrical connection
- Faulty Evaporative Emission System (EVAP) Pressure Sensor
- Faulty Engine Control Module (ECM) When is the code detected?- An improper voltage signal from EVAP control system pressure sensor is sent to ECM.

Here is the definition.

The Code P0450 indicates that the Evaporative Pressure Sensor output value is not changing during the EVAP Monitor test and/or the operation of the vehicle. This code uses "two trip" logic, which means that the fault condition must be present during two successive cold starts and vehicle operation.
The sensor is mounted in the top of the gas tank near the sending unit. You would need to test the pressure sensor.
