I went last summer. You don't need to bring the whole packing list. I went with 2 sets of ACUS but bought a third while down there b/c they get pretty dirty in the field. A camel-back will make your life a lot easier, I would buy one. You don't need the long track pants and long sleeve workout suit because it is too hot in Texas. Try to get you name tapes ahead of time (they say get 3 but i only have two, thats really all you need). You can get them at Ft. Sam but it is a little bit of a hassle, and most people had them upon arrival. You should get the amount of socks and t-shirts they recommend. Try to wear your boots a little bit before you go down to break them in. I didn't have a problem but if your feet are soft you will get blisters. If the money is a concern, you can bring a copy or your orders to wherever you get your uniforms on a base and get a military star card. this is a credit card with a terrible interest rate you can use at the PX( i wouldn't use it), but it also has a $500 limit uniform account that is zero interest forever. It was pretty useful for me. Also, about 2 weeks before you go, if you are HPSP (not USUHS) they send you a $1000 pay advance. I hope this was helpful for you.
OBC was easy,make sure to pass the PFT,, I passed it and had PT/or had to do a battalion run a total of 4 times while I was there, and got to participate in the hand to hand combat training in the field. If you fail you have to do remedial PT in the field, which looked like it sucked, and you don't get to do the hand to hand training. San Antonio is really nice.
