I would seriously get a proper bike fit. It sounds like you are way off and that will cause a lot of problems. Hopefully that fitter will suggest a proper saddle. The noseless saddles are...they are...well...they are a design I guess but the nose of the saddle is not just there because it has always been there and we hate change it is there to help control the bike. Finding the right bike saddle can be hard but your fitter can likely steer you in a better direction and also get everything at the correct height, angle and such to make sure you are comfortable. Once you have that down I would also try some Ergon grips and play around with the position on those to suit your hands but I would take care of everything else first as that seems to be the bigger area of concern.
