Question about the pregame tour at Daikin Park

Appreciate if someone can help with few questions and maybe any advise.
I have a guest from Japan, and going to the Astros game tonight.
Should be fun with Correa's homecoming as well as Bregman on the opposing end now.

Anyways, I'm now considering to add the pregame tour option for $51.99.
Below are some of my questions.

1. I bought my game tickets through Stubhub, and not through the official Astros ticketing, but that shouldn't cause any issues to "add-on" the pregame tour right?

2. For the viewing of batting practice at the end, is it not from the field level?
   I see the wording on the website as from "Crawford Boxes" or "bullpen seats", so that's where the batting practice will be viewed from?

3. Is it worth taking some items (like baseballs?) in hopes to meet some players to sign?
   I think this also depends on the answer to question 2, whether we can be at the field level or not, as that gives more chance (even if slim) to meet the players.

Below is what I see as included in the pregame tour, from the Astros website.

Witness Daikin Park as it springs to life before a game with an Astros Pregame Tour. The 1-hour tour begins before gates open and includes visits to the Upper Deck, Astros Suites, and Honda Club Level before wrapping up in the Crawford Boxes or bullpen seats for over 30 minutes of Astros Batting Practice viewing.
