Should I try out bi amp, I will use the external amp for the FL/C/FR and use pre-out with SR7008, and use SR7008 for the rear channels. And in Amp Assign, use 5.1ch(Bi-Amp) mode.
Is above correct?

Thank you very much JD!

That is correct. No problem if you set [AMP ASSIGN = 5.1/Bi-amp + Zone 2] and you use the Surr Back speaker posts to connect to the 2nd set of speaker posts on the FL/FR speakers (be sure to remove bar connecting both sets of speaker posts first though), although not likely to be beneficial.

I thought I just use channel 1 for HF and channel 2 for LF for the FL on the external amp, and use pre-out on the SR7008, and so on for the FR and C. The external amp is Classe CAV-150.
I will then use SR7008's Surround post for the two rear channels. Please correct me!

Thank you very much JD

So then, you want to use the external amp for all but your "side" surrounds (what you call rears) which you would use the SURROUND speaker posts on the AVR. Correct.

Thank you JD!

The CAV-150 can be bridged from 6 channels to 3 channels, so I thought to use the bridged 3 for the FL/C/FR, and use pre-out on SR7008, and put the surround on SR7008.
However, I don't know how to connect ML SL3 to the amp in bridged mode...
Perhaps it's better to leave everything as it is, and add more speakers in the near future.

I appreciate your time. Have a good weekend.

Adding more power isn't going to provide any benefit if the speakers don't need to use the extra power (ie. loud movie reference volume). Keeping your current configuration is likely your best option.

You working hard JD! It's 9 in the morning here in Europe.

I shall listen to your advise, and stop reading the bloody bi-amp thing.
Thank you JD, as always!
