Good to see it still works...well, despite the issue you're having.
Just to verify, is the RAM you're using a 30-pin SIMM memory? Also, iirc, some capacities are not accepted, like 8MB SIMMs for example. This RAM chart (scroll down a little further to see it) should give you some clues.
Second, are you using an SE/30 ROM SIMM or one out of another Mac II series, like a IIfx, IIci or IIsi? If you're using the latter, please note that there is a known side effect to doing that: You will get Simasimac, but only briefly, before it boots like normal. If you're using the former, try cleaning the little contacts on the ROM SIMM and its socket on the logic board. Chances are it may be a bit dirty. You can use a pencil eraser, isopropyl (rubbing) alcohol and a small wire brush (designed to be used for cleaning circuit boards) to clear out any debris.
That 'paper thing' is the RF Shield. It's made of aluminum and has a layer of plastic taped in place on the side that makes contact with the bottom of the logic board. This way, none of the contacts connect with the shield and short to the chassis ground. Technically, you can safely run it without the shield in place and the metal chassis frame is well formed to not make contact with other spots on the logic board. The case covers are plastic, so there's no chance of shorting out there.
