Is it alright to use Live USB regularly?

yes it wil decrease the life but if you have enough memory you could try booting with toram cheat code and have a separate /home/knoppix on the USB, even better get a "real" external HDD and use that instead that will live MUCH longer, downside is larger size...

Speaking of toram , is 64-bit hardware a must for doing a toram for the DVD ? Since 32-bit hardware cannot address the full 4 GBs(probably more) of memory that Knoppix DVDs require , I was thinking that 64-bit hardware is a must for doing a toram on the DVD.

Sure. 32-bits x86 processors can't address past 4GB. But if you contemplate on trying out this, I wold like to see timings, comparing, for example 64-bits toram and ordinary use of an USB3 stick on USB2 - giving ca 20MB/s read speed.
