nice - that's great gym, they have good route setters.
there's nothing wrong with 5.7. if you head outside (especially at the gunks) 5.7 is a respectable number, especially on a sport route, or even better, a lead.
remember bouldering starts at around 5.9-ish kinda, so if you're pulling a V1, you've got the ability to pull a move on a 5.9/5.10 as long as you get your endurance up to get to and through the crux.
a great way to warm up and warm down and build some good endurance is find a G0 (5.4 to 5.6) and do laps on it. don't just climb up, make sure you down climb it. routes with big open handed holds are a great way to start. at the end of the night, when you think you're totally pumped and your forearms can't get any more taught, hit that easy route and do laps (up and down without stopping) until total failure. you'll pull through some grades quicker. its also a good way to practice techniques like smearing, flagging, and general body position since you won't blow off the bomber holds.
e-stalking? nothin' wrong with that. just think of it as her way of seeing what you're interested in.
