1. Weighted GPA doesn't matter. Only unweighted + class rank + hardest courseload possible. If by "elite" you mean Ivy, Duke, Stanford, MIT, Chicago, Caltech, Hopkins, etc then you should ideally have an UW GPA of 4.0 and a class rank of top 3 (not even kidding on this one - at my school, 40-50% of students were valedictorians and another 10% were salutatorians). If you're not top 3 as a freshman, don't worry. Usually the AP courses separate the men from the boys. I wasn't ranked second until halfway through my junior year.
2. PSAT score and SAT score don't correlate very well. You're going to want to aim for 2300+, so make sure you study hard. Also get 750+ on 2-3 subject tests (unless they are Math 2 or Korean, in which case you're going to want an 800 since that's like 85th percentile and 60th percentile, respectively). 211 PSAT isn't a bad place to start, but it's not a great place to finish (for reference, my PSAT as a junior, which was my 3rd time taking it, was somewhere from 200-210, idr exactly, but my SAT scores were much higher, so you're starting off well).
3. Your ECs don't matter unless they're absolutely ridiculous (publication, founded a successful organization, USAMO whatever shit, etc). You just need to show that you've spent your time doing something other than playing video games. Having something meaningful to write your personal statement about is also a huge plus.
THAT BEING SAID...
The best thing you can do now as a freshman is keep your GPA up, take the hardest classes you can, and in a year or so, start to prep for the SAT (which you should ideally take twice). Get to know 2-3 teachers very well (preferably teachers in core classes like english, history, science, math, etc) and 1-2 adults in charge of your favorite ECs (so in this case, your basketball coach and either your Latin teacher or your Taekwondo coach) - these will be your letters of rec writers. Very strong LoRs can help you stand out from the thousands of 2300+ valedictorians while weak or mediocre ones will make sure you get glossed over.
At the end of all this, keep in mind that most of it comes down to chance and even if you do everything right you can get royally fucked, so apply to anywhere you think you'll be happy going to. Count your blessings if you're accepted and don't feel bad if you're rejected. Good luck and let me know if you have any questions.
