Hi guys, I've been reading the boards here for about a week but I haven't found the answers to some questions I have so I thought I'd start a thread and ask. Apologies if these have already been answered somewhere else. So I'm flying from Portland, OR to Columbus, OH (with a layover in Houston) on Friday, June 19th. PDX to IAH is a 737-900 (ER, I think) leaving at noon local time, and IAH to CMH is a 737-500 leaving at 8pm local time. I paid for first class tickets on both planes. So here are my questions:
1)I've been reading about FAMs being able to boot anyone from any seat. If I paid full price for a first class seat but get booted, do I at least get a refund? Or at least SOME kind of compensation? Or will they boot people who've been upgraded for free before they boot me?
2)I prefer window seats over aisle seats. I picked the bulkhead seat on the first flight (1F), but I picked the back row window seat on the 737-500 (2F). According to Seatguru, the only thing separating first class with coach is a curtain. So if I recline all the way in my seat, will I be entering someone else's space directly behind me in coach? Or is there enough room between the two that I won't have to worry about that? I'll move up to the bulkhead seat for that flight too if I have to, though it seems like there's even less legroom in those bulkheads than in the 737-900s.
3)This may be an odd question, but I don't fly much at all so I want to get the best view possible. For anyone familiar with either of these routes, is there a better view from the windows out of the left side of the plane or the right side? Or are they pretty much the same?
4)I've been reading about when meals are served during what times, but I'm still a little confused. Will I get served food on either/both/neither flights? And will they be full meals or just a peanuts-and-a-soda type thing?
5)I hear that they are slowly rolling out IFE in the 737-900(ER)s but only a few of them have it so far. Will a significant enough number of planes have them by mid-June that I have a decent chance of being on such an upgraded plane on my flight? Or is it still too soon in the process to be hoping for that? And are there at least the audio channels on both flights? I liked plugging in the headphones and listening to music on my flights in the past.
6)Are the President's Clubs at the airports open to me since I bought a first-class ticket? Or are they only open to members/frequent flyers?
Ok, that's a lot of questions. Thank you in advance to anyone who decides to answer them.

And again, sorry if these have been addressed elsewhere!
