Changing name to married name after AOS approval and GC production

[Mrsmagoo 5]

Not even sure if I posted this in the right section, if not please move. I've tried and searched the forum, but couldn't find an exact answer. Here's my dilemma:

I got married to USC and we consulted a lawyer for a bunch of questions we've had. He advised us to wait with changing my last name to my husbands until after the AOS application. So we filed all AOS papers in my maiden name. While waiting for EAD I had plenty of time on my hands and discovered on VJ that I could've just applied with my married name. I thought SSC had to be in married name in order for it to be official and in order for USCIS to find me in "the system". Now after we did our interview and got approved and received GC I'm wondering if we should file i90 to replace green card, which would cost another $450, or if we should wait two years until we remove the conditions. I really really want to take my husbands name and am kind of upset to have been misinformed by our lawyer. Could I change my SSC and DL and bank info and everything else into my married name and just leave GC in maiden until the removal of conditions? Or should I file i90 and then change everything on all the other things like DL? I'm just so confused by what step to do first. Any help and suggestions are greatly appreciated.

I would wait the 2 years to change your GC. But you can change your SSN card by taking your marriage certificate down to the SSA office and requesting the change. Also bring your marriage certificate to chance your DL, bank account, etc... the only time after that you will need your marriage certificate will be for travel as you should book any plane tickets travelling outside the USA with your passport name. Any travel inside the USA can be booked with either green card name or DL.
