You shouldn't have to be a split second of so off. You can right click on the wav form and it will set Bar 1 right where you clicked. Then, you can hit F8 for the start of each bar, but you can easily move the markers after the fact to get them exactly where you want them.

If BIAB is playing a style along with the imported MP3, and you don't want that, then you need to disable the style (you'll see a red X showing it's disabled). Then you will only hear the MP3 file (played on the audio track).
