To concur with Stan, student loans don't consolidate unless it's a federal loan consolidation or you get behind in some way & the private loans apply a repayment plan. You say you have $30K in private student loans. Number 1 thing is figuring out if you need/want more school in the next 10 years. Since we don't know the actual loan terms, here's the most likely options.
You haven't started FT, so I would wait until you have a FT job with strong cash flow. This way you can budget. Know, it takes a few weeks for consolidations to go through in almost all cases, so if you have an offer sheet, you might start the process right after you start work. Many jobs take at least 2 weeks before payroll kicks in, so don't want to have payments start with no income.
If you don't plan on going to school anytime soon. Just repay the loan & do an AR b/c it's the lowest interest.
1) 2 year pay off - probably $17500 a year (rough estimate including interest). Adj. Rate is fine.
2) 5 year pay off - probably $8,000 a year (same rough estimate). adj. rate is ok. Fixed offers protection.
If the loan offers deferment options & doesn't accrue interest during school, then you might consider not repaying the loan in full to save for grad school expenses. However, THIS IS ONLY IF YOU KNOW FOR CERTAIN YOU'RE GOING TO SCHOOL AGAIN. Otherwise, kill that loan. I would personally pay it off anyway as student loan debt is dischargeable in bankruptcy & lenders can make life hell for you if necessary.
