Can cisco NOT perform reverse lookup in MAC table when installed in layer 3??? I heard it only works in (Transparent mode) function, which means no NAT/PAT and VPNs. Is that true or not? Can you please guide me to a link?

Correct, no reverse lookup in MAC table in routed (layer 3) mode.
Transparent firewall does support NAT now, but still no VPN termination support for transparent firewall.
NAT support in transparent firewall:
