Hi,
Well, once you submit the status report from FCCPT then USCIS can make their own decision but advantage can be the time for them to make decision because during the time USCIS reverts back to you, you may have FCCPT certificate which you can submit.
My best advice to you would be to reach out to your local congressman's office as you do not want to get in trouble at this last stage. We also took support from our congressman's office and it helped us big time. There is always a person at congressman's office who takes care of immigration process, and there is a congressional person sitting at immigration center i.e. in Vermont center or Texas whichever is relevent. Now you can write a simple application about your case, like a letter and explain to congressman, that your case was filed on such date, give EAC nos and add a copy of your receipts as proof, explan to them what is your category - schedule A and why FCCPT certification is required and give a copy of your RFE also, basically your whole case, and explain in a manner a layman can understand but with EAC nos and proofs of receipts. Then ask for their support in your case, once you have this, go and meet the person in congressman's office and inform him that when you will get a status letter from FCCPT, you will send it to USCIS but will also give a copy to congressman office which they will forward to the congressional person in USCIS for follow up and they will bring you feedback also how they are processing on your case, in this case, it helps because sometimes USCIS people make hasty decision but the interception by congressional person makes them slow and makes them think, you will get a call from congressman's office to submit the real FCCPT certificate soon as possible and they will try to support your case so it won't get denied but incase if it gets denied then your congressman knows about it. Now if god forbid, your 485 gets denied then you can appeal and still continue to stay here, and make an appeal to AAU - administrative appeals Unit in Washington DC who has right to revert USCIS decision. Again Congressman person will help you as they have congressional person there too in AAU and they will expedite your case and will bring you positive response.
We have been through similar situation for our 140 denial and our congressman office helped us a lot and also helped us get through 140 approval and now we responded with our FCCPT certificate to USCIS for 485 RFE. Without us calling our Cong. office now, they are only following up on our case.
Point is : whe it comes to USCIS - it is a blank wall and we have no way to contact them about case but through congressman's office, you can find out about your status at every step and before time you can get idea what may happen or if they need more document.
Follow this link and find out who is your congressman - House of representative
Keep trying. I know its very frustrating. Try to contact your House of Rep. Write something touchy.
Here to find your House of Rep:

Put your zipcode, and you can find who your rep is. Do send just to one address. He/she may have more than one address. Make sure that he/she read your letter.
Hope this helps, Also anyone you know is having problems with H1b or Green card, suggest them to go to their respective congressman's office for help, they are there for our service and there is a person designated to handle Immigration issues for people living in their area. Make use of this.
Wish you all the luck.
