I CHANGED FROM F1 TO H1 LAST YEAR OCTOBER 2004. I CHANGED EMPLOYER IN JUNE AND GOT MY VISA APPROVED BY THE SOFTWARE EXPERTS GROUP INC. NJ.THEY ARE NOT RELEASING MY H1 PAPERS AND THEY MADE ME SIGN A CONTRACT IF I WANTED TO SIGN THE PAPERS. I NEED TO GO TO INDIA IN DECEMBER SO I NEED MY PAPERS ASAP BUT THEY ARE ADAMENT ON GIVING IT TO ME. I HAVE FOUND ANOTHER EMPLOYER BUT I HAVE ONLY ONE PAY STUB FROM JULY AND I HAVE NOT RECIEVED PAY AND PAYSTUB FOR THE PAST 2 MONTHS.PLEASE LET ME KNOW OF ANY OPTIONS THAT I MAY HAVE. THANK YOU.

file for another h1B with new employer, attach the old Salary slip , write a letter that your old H1B employer did not have job for you.
once your new H1B is issued you can travel, till then you should wait.

Is there a way I can get my H1B petition from INS? Also my current employer is not paying my salary. Is there anything I can do to claim my money legally without much hassle?

there is no way to get H1B by yourself. its employer who retains it.
yes there is a way to get salary, you must be sure that your H1B is approved by the same employer.

get your status first then hire an attorny, it will be complicated to explain here.
