Plugin Question... Native VS TDM?!

[minor2nd]

From my understanding, i've always thought that i cant use the TDM versions of the Waves plugins. I thought because i had the 002r and pro tools LE that i could only use the "native" versions. Im confused because i saw the Waves Masters Bundle for sale and in the auction the guy says the TDM versions he's selling will work with the 002r... i guess meaning with LE? Whats the difference between the TDM and Native versions. I thought one worked on the TDM systems chips, and the other used the computers CPU?!?!? Please make me understand.

Also i have some plugins with my 002r (ff d2 and d3's), that need the "i-lock" to authorize them. Did these come with my 002r package? How do i authorize these without "i-lock"?
