The Daily Prayer Book By Dr. Joseph H. Hertz

One Publication that I have found very helpful is the Authorised Daily Prayer Book סדר תפלות כל השנה by Dr. Joseph H. Hertz the late chief rabbi of the British Empire. The text is in Hebrew and English with commentary and notes. Each prayer is translated and explained in great detail making the daily commandment of prayer much easier to accomplish and understand. The prayer book is usable for the entire year including all holidays as well as everyday. I strongly recommend it to anyone regardless of level of understanding. Rabbi Hertz writes this siddur for the common man to understand and does not talk over the readers head.
