I think you will find the resources in this thread http://discourse.textkit.com/t/help-me-find-resources-for-caesar/17786/1 more helpful than the Loeb.
Steadman the Dickinson college commentary and Kelsey are all available on line and will give you a lot of help. If you need more ask here. The Loeb will give you no help in understanding the Latin. Working back from a translation is not helpful when you are learning Latin. As a last resort its ok when you have exhausted all the possibilities but it too soon becomes a crutch.
Did you recall this thread which mentions the new translation by Jim O’Donnell http://discourse.textkit.com/t/how-to-read-caesar/17686/1 It is better I think than the Loeb which dates to 1917.
