If so, will the older devices see any benefits from 802.11ac access point?

Yes, there is backwards compatibility, so you should be fine with older devices. There might be some differences noticed in range. Depending on the number of devices using the same access point, you could actually see a decreased range.

You can get more background info about 802.11ac here:

http://en.wikipedia.org/wiki/IEEE_802.11ac

"IEEE 802.11ac is a wireless computer networking standard of 802.11, developed in the IEEE Standards Association process,[1] providing high-throughput wireless local area networks on the 5 GHz band[1]. The standard was developed from 2011 through 2013, with final 802.11 Working Group approval and publication scheduled for early 2014.[1] According to a study, devices with the 802.11ac specification are expected to be common by 2015 with an estimated one billion spread around the world.[2]

This specification has expected multi-station WLAN throughput of at least 1 gigabit per second and a single link throughput of at least 500 megabits per second (500 Mbit/s). This is accomplished by extending the air interface concepts embraced by 802.11n: wider RF bandwidth (up to 160 MHz), more MIMO spatial streams (up to 8), multi-user MIMO, and high-density modulation (up to 256 QAM).[3]"
