For 1 and 2, on what basis do you select channel 3? DD-WRT is somewhat stable if we count in the few bugs that arise from time to time.

Have you tried Auto as channel selection?

Remember that there are other things using the same frequencies such as cordless phones, baby monitors, bluetooth etc etc.

Regarding question 3, good security with strong encryption/passwords.

in mikrotik there is a tool to test usage of the freq.
is there in dd-wrt a tools like that?
