What will I need to bring with me to 88M AIT (Split-Op)?

I've tried asking my recruiter but, no one at the station seems to care about anyone who isn't going active duty. So, instead I will ask here - what do I NEED to bring with me? Do I need to bring everything I was issued? I will be leaving August 11th, so I don't expect the weather to be cold. I'm trying to cut down and only bring what I need - rather than having bags full of junk that I didn't need to bring with me and can purchase at the PX once I arrive. On a side note - what items am I not allowed to bring? As a split-op, my only experience with training is from BCT, where electronics were not allowed. Are cell phones or other electronics allowed?
