First off 4 line LCDs are really 2 line Lcds which are laid out thusly
Line 1 & Line 3 are line 1
Line 2 & line 4 are line 2. Just FYI
Try moving the E bit off PortA.4 I believe that is the MCLR pin with open collector see if that works, quick test anyway.
If so you might be able to use it with a pull up. I always ground pins 3 & 5 unless you really want to hassle using a contrast control or really need to read what is on the display.
Edit: I do not see any config statements, so you undoubtedly are using the default configs, do you know what they are ? Do you know how they are set as default ? Do you know where they are ? If the answer to any of those questions is no then goto this link: http://www.picbasic.co.uk/forum/showthread.php?t=543

Prepare as a nonbeliever. If your belief is incorrect you will be prepared, and if your belief comes to fruition, you have prepared the nonbeliever, who occupies your home, to survive tribulation.
