Yes, absolutely, but I'd like to be able to hook up multiple sprinklers to the same hose and have them work effectively. I also like the idea of being able to water my garden with a fire hose if I'm short on time. I'm also kind of thinking that if I have the opportunity to make the system overkill for a few extra dollars, why not?

3/4 hp

Unfortunately I have no idea.

The pump is in my basement, it's right next to the pressure tank, filters, etc. I'm also hoping the oversized pressure tank will make up for the potential shortcomings of my pump situation.

Pumps like this are quite sensitive to how high they need to lift the water.

Personally I'd suggest doing a test on the pump/sprinklers first. Just connect the pump and existing pressure tank to a 3/4 hose fitting, run your hose out to the sprinkler, and make sure the pump and well can run your sprinkler. This lets you know if new piping will fix your issue or not.

If the pump does not keep up to a sprinkler, then either it's lifting beyond what it's rated for, or it's badly worn. Some wells tend to pick up a little sand, and the sand chews up the impeller. Or if the pump ran dry for a while.

A larger pressure tank reduces how often your pump needs to cycle, but if the pump can't keep up then the pressure will just slowly drop off. So if your pump just runs (doesn't cycle on/off) the whole time you have a sprinkler going, then a larger pressure tank is not very useful.

Bypassing the filter and water softener will help for sure, and save you money. No point carbon filtering and softening water for the garden!
