Since you have a built in mic, I don't think you can plug a mixer into your deck. "Phono" may be for headphones, in which case it's an output, not an input. You're doing this all yourself, so the mixer shouldn't be a factor unless you want to record more than one input at a time, which I wouldn't recommend with what you have. My advice is to forget about the mixer, at least for now.
Put a blank tape into the recorder side of the dual cassette. Plug headphones into the Phones jack, hit record (with some boom boxes you have to hit the record and play button at the same time), get behind the drums and have at it (make sure you hear the drums in the headphones). Stop the tape, take it out and put it in the play side of the tape deck and rewind it to the start of the recording.
Put a second blank tape in the record side, press pause, press record (or rec/play). It will be ready to go, but paused. Get your guitar on (still using the headphones) and press Play on the first tape and Pause on the new tape to release it and start the recording. You should hear both the drums you recorded and the guitar you're recording in the headphones. When you're done, the second tape will have both drums and guitar on it. Switch tapes, cue the drum/guit tape to play, and start recording on the first tape using blank space (don't tape over the original drum track, you may need it again before you're done). Now you'll be hearing the drum/guit on the play tape and you can sing into (near) the built in mic on the boom box and you should hear your voice being recorded with the drums and guitar.
This process is not strictly multitrack recording, it's called sound on sound. Using a built in mic will introduce hiss right away (and probably clicking noise from pressing buttons), and the more "tracks" you add, the more noise will be introduced. It is far from ideal, but it can be a lot of fun, and it's really the music that counts more than the quality of recording. I'd rather hear Bob Dylan recorded with this setup than Celine Dion recorded in a state of the art studio. Don't fret about the mixer, you may find a use for it down the road if you can't find a way to use it with the box you have now.
Experiment and have fun!
