Flush and decontaminate the tub and then fill it and balance the water , then see if you like the tub the way it is, if you dont, get another one, but if its already there, it works, and its hooked up then that would be a big plus for me...
i wouldnt remove the jets unless they are broken, if you do in my opinion your asking for a leak or to break something, just do a really good decontamination and bleach everything and buy new filters and you will be good enough to find out if you like this tub or if you want another...
but keep in mind if you get a new one you will have to make sure it is the same size or just a little bit bigger so it will fit the existing hole for the current tub..( you could do a smaller tub but you would have to frame it in and it could be an eye sore
