Basic bike fit is just the triangle formed by bars, saddle and centre of bottom bracket, if the frame is even remotely near to fitting you it should be possible without too many adjustments and costs. The Seta is a track frame, so it will be stiff, fast and unforgiving. You just have to sacrifice comfort for speed, it simply isn't designed for long distance riding like a road bike is. If you want your power to translate into the maximum forward motion you need to ride with a flat back, sometimes your back will hurt, tough! Sorry, but we've all had to cope with this uncomfortable fact and come to a compromise....
