IAH is an easy airport to navigate.

You will almost certainly arrive in Term E, and according to reports in this thread should breeze through Immigration with GE.

LAX will depart either C or E, and even gates far away are no more than 15 casual walk.

IIRC posters report that Pre is closed in E after certain time, so you may not be able to take advantage of that to get back to secure area.
