Quick Update:
Ran the installer with Mavericks 10.9 GM using the Extra folder with an updated graphics and applehda kext, still no luck with sleep/wake on lid nor the webcam or microphone registering at all with the system. Any possible ideas as to why this is happening? I have an identical t410s to the one described in the guide (Whitelist-modded 1.50 BIOS, Type 2904, Intel i5 560 M @ 2.66 GHz, Intel GMA4500 Graphics, 8GB DDR3 RAM @ 1333 MHz, 127 GB mSATA SSD, Stock & CD-Bay Batteries installed)
The only notable difference between our systems is that my model didn't come with a fingerprint scanner or an SD card reader like some of the t410s' have.. So I'm at a bit of a dead-end here. Any further help would be a lifesaver! I'm really new to putting OS X on these machines and would love to understand what is missing or needs modifying to get this system 100%.
Other side note: Tried to replace the AppleHDA using kext utility with the absolute newest one you put in your post, killed audio on my system, had to roll back to the previous version. Update: Tried using the newer version after rebooting and things seem a-okay. One other side-note, I've noticed that under audio devices a non-working "Internal Microphone" pops up.
