IT is very hard to change ur B2 to Student in the states now. While you are in the states and waiting for Green card, you need to have legal status urself. not just waiting.
For your case, it make no BIG difference whether you r in the states or not. it does get quicker, but not too much. You only save Interview time in Guangzhou.
It is NOT hard to get B2 in China now, so your mom should be fine. For your B2, you need to find out what did ur mom do to your old B2 to keep you legal in the states, Visa officer may question you on that. The only possible reason is your mom changed your status to J1 for you to go to middle school or F1 if you went to Private school.
One more thing, you need to tell ur Dad to file I130 as soon as possible because if he files after u turn to 21, your immigration preference will be diff, which means longer wait.
Since ur Dad is a green card holder, so your and ur mom greencard wait time is at least 5 years now, which means it even slower than ur dad become a US citizen, your dad can apply US citizenship 4 years and 9 months after the date on his green card. Once he become US citizen, he can request USCIS to change ur preference, so the case will be process right way.
