Help a Blogger Sista Out

I am new to the blogging game so I am not sure what's going on. . . help me if you can.

Issue #1: Cannot add new links to my blog roll. I go, I add them, I edited out the doubles plus the spelling error on "What to expect when you're not expecting" and get the error message that my changes cannot be saved. Why?

Issue #2: My dates/times are screwed up. I have several posts under the same date/time, but they were made on different dates at different times. What's up?

Thanks much!
