There aren't really any vet schools that are objectively "easier" to get into. Possibly SGU and Ross, partially because they each have more than one class per year. The best thing to do is going to be to look at how each school evaluates applicants, as well as average statistics for recently admitted classes, and decide which schools you would have the best chance at based on your stats. For example if you have a lower cumulative GPA but high science and last 45 GPAs, there are some schools that weigh those more heavily than cumulative (or don't look at cumulative at all!). If your stats aren't absolutely stellar, maybe don't apply OOS to schools that only take a few OOS students each year (e.g. Texas A&M). Individual school websites are the best place to find this information, but feel free to call or email admissions departments if you have questions. Your best chance is always going to be at your IS school if you have one.
As far as tuition assistance programs go, some schools offer more scholarships than others, but it's pretty hard to predict, and the timing of how to apply for scholarships and when scholarship offers go out varies depending on the school. But in general, it's uncommon to get a scholarship of more than a few thousand a year. I know there are a few people on here who have gotten very generous offers, but it's not something you can count on. Bottom line, go to the cheapest school you're accepted to. Schools may have a financial advisor available to advise you as far as taking out/paying back loans, but for the most part that's on you. My advice is avoid private loans, federal loans are going to have the best repayment options available. Some states have tuition reimbursement programs if you're willing to practice in a rural county, but I know at least for Kansas it's really competitive, and they prefer to take Kansas residents. There's also the Army scholarship (again, very competitive and of course requires a few years in the service), or PSLF which unfortunately may be going away, and there are a lot of requirements you have to meet in order to actually get your loans forgiven.
