You can run the same shocks after doing the lift but the tolerances will be off so the ride will be really harsh, you'll feel it bouncing a lot more than it should, and if you get too aggressive with it (Blasting down bumpy rocky roads or hitting potholes or speed bumps without slowing) you stand a higher risk of blowing a shock out.
More importantly though, after doing the PML you'll want to have an alignment done. That won't matter much with the BL since it doesn't affect the geometry of the suspension at all.
As far as the tires go, it won't have as aggressive a look to it until it has bigger tires with a deep tread, but I wouldn't go so far as to say the tires will look tiny. Just it will look much better once the whole thing is done.
Hope that helps
