st: Testing the Significance of Differences Using Traditional T-Tests & Bootstrapping

Dear All,
I am in the midst of writing my dissertation and I need to test a few things but being relatively new to Stata I need a bit of help.
Long story cut short, I have 9 variables that have different numbers of observations and I need to test the significance of the difference of the mean, 10th percentile, 25th percentile, median, 75th percentile, 90th percentile, and the percentage of positive observations for 2 variables using traditional t-tests as well as bootstrapping.
Testing the significance of mean differences is ok. I guess I just have to use the 'Two-sample mean-comparison test'. My only question re. this test is; should I tick 'unequal variances'?
My real problem though is testing the significance of the difference of the median, 'x'th percentile, and the percentage of positive observations. How should I go about testing these using t-tests and bootstrapping?
Thank you very much indeed, your help is greatly appreciated!
Kind regards,
C.
