chances???/recommendations

<p>i'm a junior, and have this spring begun to take the initial steps in the college process.
i took the PSAT my sophomore year; though i'm not sure of what specifically my scores came in as, i recall my writing being good (96th percentile?), reading being pretty good (somewhere between 91st-93rd percentile), and math being quite poor.
took the PSAT during the fall of this year and recieved scores of 60 on critical reading, 46 on math, and 63 on writing. the sheet on which i recieved my scores indicated that i had qualified to be in the running for some type of national merit scholar thing, but i never pursued it and doubt it would ever go anywhere - honestly, it may have been a typo on the page.
took a mock-SAT practice test with no prep this spring and recieved a 620 on critical reading, 460 on math, and 700 on writing. took the SAT a few weeks later; though i havent recieved my scores yet, i plan to do a great deal of work this summer to help bring up at least my math score, and hopefully the others as well.
finished my freshman year with an average of 73. finished my sophomore year with an average of 77, and will be finishing this year with an average of 91.75. i took my first AP english course this year, AP english language, and am enrolled in AP english literature for my senior year. i'm involved a handful of extracurricular activities, will be a prefect, and hold a one or two other leadership positions.
my serious considerations are Sewanee (as i am especially interested in their english program) and CofC. i will also be looking at, but am not quite as interested in, Boulder, Colorado College, Vermont, and the University of South Carolina. Do any of these sound realistic/within my reach?
also, being far less realistic and admittedly idealistic, i added a few of the following to my "colleges i'm considering" list: NYU (would kill to be part of journalism program and love the artsy/city vibe), University of Richmond (have a few family connections there..probably not enough to make a difference), Tulane, Southern California, etc - obviously this is really stretching it, but does anyone have an idea of how far out of reach these are for me, or of schools that would be similar in type but more realistic?</p>
