For barbell training, Starting Strength is a fantastic introduction.

For kettlebell training, I would sooner look to Pavel Tsatsouline's Simple & Sinister for a simple and effective program that can be run by beginners for a good long while.

My pointers to you: 1. full range of motion, 2. form follows function & 3. do exercises cleanly!

My number one pointer would be: Don't be afraid to scale either the routine or the exercises done.
