Hello and welcome Henry_Porter,
I am in my second year at Cal State Monterey Bay and so far everything mentioned sounds great. Something I would add is a good sit down talk about what you expect from the college bound student. Topics should include grades, sex, proper behavior, finances, drug/alcohol and any topics you feel are important. Also do not forget to tell them to have fun, make smart decisions and that you love them no matter what.

In addition to this, a really good mattress pad is a good idea. I just got a Geo-Pad by Span-America Medical Inc. it is the best thing ever. I think my dad got it from a Medical Supply Place. A good set of tools for the car that he never lends out and a cheap set, from target for the dorm room that he can lend out. Send a few good, microwavable dishes. 2 sets of sheets for an extra long twin mattress. Do not forget that space is very limited in the dorms and most of the affordable housing near campus. Make sure you let him pick out these things and be there willing to give advice. I remember my parents kept telling me what I should get and it was very frustrating.

Hope this is useful.
