Also i would consider selling the lenses you have to upgrade as you have 2 lenses that overlap the same focal range and i believe your Tamron might be 3.5-6.3? and Canon NON IS and 4.5-5.6?Both are slow,im not sure what type of photography you are doing but a fast 2.8 or faster is always a plus.
Also always shooting in Manual mode is a must for accurate results.
