3 engine codes: P0135, P1739 and P0171
I already know what the codes are, I want to do most of work myself. I want to know what the least expensive approach to fixing the codes would be. I was thinking of cleaning the fuel injectors and changing the transmission fluid. I have a 1998 Honda Accord by the way.

V6 or 4 cylinder? The 01739 is for an automatic transmission.
You need to do some diagnostic work to figure out the actual problem(s).
P0135 is the heater circuit of your O2 sensor, so you would want to measure the resistance on the O2 sensor to see if the heater circuit is open. This could also be a wiring problem.
P0171 is a lean condition, so there is too much air or too little fuel. Do you have a scan tool that can read fuel trims or O2 sensor output?
The P1739 is for the 3rd clutch pressure switch. You would need to test if the switch is bad. This could also be due to wiring or something internal in the transmission.
