I recommend the IVP New Testament Commentary Series:
Pastors with a passion for sound exposition and scholars with a heart for pastoral leadership have joined forces to produce this exciting commentary series. Each volume, informed by the best of up-to-date evangelical scholarship, presents passage-by-passage commentary based on the NIV along with background information on authorship, setting, theme and various interpretive issues. A unique format allows the main commentary to focus on the vital message of the New Testament for today's church, while bottom-of-the-page notes include valuable scholarly information to support those who use the volumes as a resource for preaching or teaching preparation.
The Grace Commentary. "A Free Online Bible Commentary". As of June 2015, includes Luke and Jonah.
