We could, and probably will, make this more complicated than neccessary.
I do believe that a very strong DL will carryover to a strong clean. Regardless of order, cleans and deads complement each other very well.
Back to the original posts: If you want to become very good at these lifts you have to train them on more than one day. I did the following split last summer and showed huge gains.
Monday- Deads (Phillipi/Coan routine) and Squats (1 set of 5)
Tuesday- Bench and dips
Wednesday- Hangclean (5x5)
Thursday- Pushpress (5x5)
Friday- Power clean (max effort 5 singles w/lots of rest between)
Saturday- 100 rep clean and press
Sunday- Rest day
