1.  Ill tell Anna all the news when I see her. In the conditional clause we use Present Tenses after the conjunctions if, when, as soon as , etc. It is important to remember, that while we use only Present tenses, the action in both clauses refers to the future. 

2.  He reminded me that we had been classmates at school. There are at least two reasons to use Past Perfect in the reported speech. First, after the verb in the first sentence is in Past Simple, so according to the rule of Sequence of tenses, we must use Past tenses also in the reported speech (there are some exceptions). Second, we use Past Perfect to denote an action in the past (had been classmates) , which happened before another action in the past (reminded).
