Tips on what to do from here?

I'm a 2nd yr undergrad majoring in bio sci and animal biosci. i'll be applying in less than a yr and a half and wanted to ask if there was anything i could do now to help improve my chances, just wanted to hear your thoughts

3.63 gpa (I did poorly in ochem 1 but i'm hoping to make a comeback next sem)

\~520 hrs of combined animal and vet experience (was vet assistant for three months full time (320 hrs) and then kennel tech for 5 months part time (200 hrs)

\~85 hours of research experience with swine\~125 hours working at a horse barn, mucking stalls and stuff

\~100 hours research with a parasitology lab

I just don't know how to build good connections to get a solid LOR, I was going to choose a professor and then two vets but I have to find a vet job and then stick with it for a couple yrs. Should I focus on research and work on getting a research paper published or maybe do more working in a vet hospital or just soley focus on my gpa for the next semester or two? I just don't want to jump all around the place and then not have any good sources at all.

Edit: it might just be my imposter syndrome or smthng but I just feel like i'm so behind my peers when it comes to getting experience and making good grades and it stresses me out bc i know the vmcas is right around the corner and i know vet school is super tough
