First of all I can assure you there is an EGR, at least the repair manuals show and I have one on the car I own with the same engine. Now, the O2 sensors. They are so simple to replace. One is a little tougher that the other but you could replace them one at a time. I would start with the upper one which the easiest and is located above the cat converter on the exhaust manifold. Go online and search for a Honda O2 and you can hunt down the O2. Stick with an OEM that has the connection and does not require you to use the old connection. Do not get a universal one. About $60 to $70 each. You can do it. If you have the replacement in hand, take off the electrical connection and then cut the wires above the O2 leaving about 2 inches of wire and cutting with an angle. Put on a socket to remove the old O2 and install the new one using an open end wrench to tighten the new one in to the exhaust manifold. Connect the connector and you have it. Pretty much the same process for the lower one too. I cut the wires above because it still allows the sensor to be re-used in the future for some unknown reason. The angle cut allows you to easily tell which wire connect to which on the O2.
Don't be afraid to try it yourself and save a lot of $$.
