I think vinny's reply says all. Let me try to answer you in simple terms.
Your questions show you need to get thorough understanding of Tier 4 visa procedure.
A dependent cannot extend visa on their own, if your visa gets extended, theirs will get extended too.
Tier 4 visa is for a student who has been offered admission in an UK university. If you plan to bring wife and child, they'll be termed Tier 4 Dependents. (Only if your course is more than a year you can bring dependents, I think.)
Your partner is allowed to work full time as long as your Tier 4 leave is given. No way your partner can apply for extension, as he/she is still termed a Tier 4 dependent. If you switch over to another course, her visa validity will be extended.
Put it simple, your partner has been given visa based on yours but not on the work he/she has taken. Again I say, if your visa extends, then theirs too. You are the main applicant.
Getting citizenship is based on your visa and time spent in UK. Right now, 10 years required for ILR, long residency route. First you need ILR and then only citizenship. It won't happen automatically, you need to prove your worth and get a sponsor for CoS.
