I agree that for a simple, quick battery change, don't risk damaging those delicate wires. Ignore Step 6 and instead of disconnecting the mic and camera wires, keep them in place and just have a friend hold the plastic frame up while you change the battery, or prop it up as mentioned by Stefano C above.
The T8 Torx does *not* have to be security type. However it is critical to have a long, thin, dedicated T8 screwdriver, not one that is part of a kit with interchangeable tips (and thus a thick collar that won't fit into the narrow slot). I got the kit, it didn't work, returned it and got an unmagnetized T8 with 2.5" length. I then magnetized it with a strong refridge magnet (which didn't work well), so better yet after I removed the 8 screws (Step 11), I magnetized the screws themselves, which worked great.
