As far as "Disciple of Life" goes, go into the properties of your cure wounds spell and add +3 after the 1d8 that it heals and also add +1 for higher level cast. No macro needed. When you get "Blessed Healer", I would just add it as an ability in the lower right section of the sheet and remember that I get healed when I heal others. You may get a better suggestion for that. For "Preserve Life", I'd keep a pool of heal points in the class resources and use it from there. I think that's what most paladin's do. You could include an ability in that lower right section for that as well. For "Divine Strike" turn on global damage modifiers and create an attack there. For "Supreme Healing", just change the amount healed in the properties from a roll to the maximum.
