Starting down into the San Antonio area; ATC started down with a tight crossing restriction on an arrival. Once being sent direct to a couple of fixes; we were then being vectored instead. Autopilot was not engaged. The Captain setup the RNAV approach into RND and we exchanged controls; so I could then brief the approach. As I briefed the approach; I heard a 'ding' as the altitude alerter went off at 400 FT below assigned altitude. ATC advised us to climb to 5;000 FT/assigned. Once stable; I finished the brief and took the controls back.Next being vectored for the RNAV; we were assigned an intercept heading which made joining final require more than standard rate. I banked to try and intercept; but started to lose altitude in the process. ATC advised us of a low altitude alert again. The Captain helped me at the controls and to get back to being stabilized. Once on stable; we followed the GPS and altitude restricts on the approach. Just before we broke out; ATC advised us once more that we were way off course on the non-precision RNAV. We broke out as they advised us and we told them we were stepping over to straighten up on final. The GPS indicated we were on course the whole time.
A First Officer with low time in his aircraft type reported difficulty flying an IMC RND RNAV approach and experiencing both altitude and track deviations about which ATC issued advisories.
