If your question is whether you should send additional documents in connection with the Form I-102 you have already filed (i.e. mailed), then I suggest that you actually wait until you hear back from immigration. Even if you do send additional documents after filing the I-102, it is likely that the additional documents will never make it to your immigration file for this case. While it might have been helpful to send additional documents with the initial I-102, at this point I would wait. You may call the toll free number at the bottom of your receipt for the I-102 to get an update on the case. You may also check on the status of your case online at www.uscis.gov.
I agree with my colleague -- sending additional documents after filing but before a request for evidence would not be very helpful. Even if you send a copy of your visa now USCIS may still ask for additional evidence.

It is too late to send in more evidence now ... it will get lost in the mail room.
Wait for them to ask ... they will send a sheet with a bar code ... to make tracking easier and reduce the risk of loss.
Yes, it takes a long time ... that is the unfortunate price you pay for having lost your I-94 ... sorry.
