This Is My First Time Playing Stardew Valley Expanded

So, as the post says, this is my first time playing Stardew Valley Expanded. Like my first Stardew Valley game, I intend to avoid the wiki so I can discover new things. But I have a handful of questions.

Will the community center item bundles (I selected remixed) include items from SVE? Or will it just be items from the vanilla game?

Secondly, do you have any general spoiler free tips for me? Any normal Stardew habits I should break?

I should note that I'm on the frontier farm. I do like that there are clear paths up to the mountain and to Cindersap forest. I also note that Cindersap Forest is MUCH larger than in the base game, which I like.

UPDATE: Thanks everyone, for your advice! I'm now up to the egg festival, and things are coming along well.
