Good day Picers

I have always done my programming with the Microchip picstart plus for DIP PICs.

I want to do In-circuit programming on SMD PICs now.
What are the best options?
I see Microchip have a "MPLAB REAL ICE" and the "MPLAB ICD 2".
Are these the best programmers to use and what else do I need.
Do I need any changes on my circuit side?

Thank you
