Hello and welcome to the Forum - a little advice as you get started:
Use the search function in this part of the forum - all of the people you have mentioned have commented on all of the above ideas on multiple occasions. You will see plenty on application process/advice, cadet life, post-graduate experiences, etc. all the way down to trivial advice on what underwear to bring to swab summer.
Comb through the USCGA website thoroughly, there is a wealth of information to be had - and they just redesigned the website with a lot more information added. You're getting information from the formal source vice anonymous posters on a forum.
If you have not already, contact your assigned Admissions Officer (info on the website), let them know who you are and your interest. Ask if there is anyone in the area you can speak with - USCGA retains hundreds of volunteers known as Academy Admissions Partners - we are available to assist you in your process and also conduct your interview (in person or via Skype/Video Chat).
Bottom line, ask questions - but make sure you also research on your own. It's a skill that will set you up for much success later one.
