Yeah, you can save it, but it will take a lot of work. A lot.
A no. 6 or no. 7 would be best. Get a set of winding sticks and check your work frequently. Get your plane blade honed to a perfect edge before starting. Might need to touch it up mid-job.
When you’re ready to get a table saw (best option for ripping), read up on tablesaw safety. They’re powerful, and they can kick back the workpiece with disastrous results. My daughter, the hand surgeon, reattaches fingers every week, but some injuries from table saws are too severe to be fixed.
My advice for a tablesaw is to go with an entry level contractor’s saw with a good fence. Something like this: 5000 10-in 15-Amp 120-Volt Table Saw with Fixed Stand

I know it’s expensive. You can get a tabletop (AKA Job site) saw for much less, something like this: 10-in 15-Amp Corded Portable Jobsite Table Saw with Foldable Rolling Stand

The tabletop circular saws use a universal motor, and they don’t have a ton of torque. It’s easy to overpower them, and their lightweight means that when you’re pushing on a piece of heavy stock, they can shift. They’re OK for small jobs but not for ripping big boards.
For your 2x4 pine, they’re fine. For bigger stock, or hardwood like Oak, they’re inadequate.
A contractor saw should have a cast iron top, with an induction motor, that’s hanging out the back, and that’ll have a lot more torque. The increased weight of the saw, and the increased torque of the motor, make it a lot safer for ripping.
Blades have gotten pretty expensive, but if you’re actually gonna do a fair amount of ripping, you want a dedicated ripping blade. Get a good quality ripping blade. Forrest makes the best, Freud is decent. Get a combination blade for most work, but a ripping blade for ripping.
Figure out what you’re intending to do for future projects. If you’re planning on doing the kind of work that you’re doing now, then you won’t need the increased power and weight of the contractor saw, and the table top will do well.
The best is an actual cabinet saw, like this: 10-in 15-Amp 115-Volt Corded Contractor Table Saw with Fixed Stand

Power and precision for any task.
Whatever you choose, spend the money on a good blade.
