I'll reply to my own message regarding 2) since I have found more information:
More sucess from forum members with the 3.0 verison, less with 2.4 version, and only 1 post I could find regarding a 2.4 hybrid ATH10W.
Based on what I read here, Success varies with ELM327 bluethooth adapters because it is suspected because cheaper/knockoff units do not have a required chip/function to read our JDM vehicles.
In the case of using Torque Pro as the app with a fully functional ELM327 adapter, Some have reported a need to enter an additional string code. Others make no mention of a string code. In one thread, a poster stated the following string was used for a 2003 2.4 alphard (non hybrid) and worked: ATIB 96 \n ATIIA 13 \n ATSH8213F0 \n ATSP4 \n 0100
Others stated that they had success with using Car Scanner ELM OBD2 App by 0vZ with the ELM327. The following Profile was used: Toyota JOBD JDM CAN
Multiple reports of success with the 2.4 Alphard (not sure if hybrid is included) and an off the shelf ANCEL JP700 JOBD OBD2 Japanese Car Scanner. No details as to if any customization or profiles used... or if it just works.
Please add more information if you have it. Thank you.
