Answer 1

I compelety agree with @Amokrane's answer but insure that your database should also have backward compactibility. Because you are saying that your database is properly normalized (FK , PK etc). And here Foreign Key support is only available since the SQLite version 3.6.19 therefore this constraint could only be applicable on the Android 2.2 FroYo (which has SQLite 3.6.22 Version) and the above versions.

Answer 2

This official SQLite limits page contains many information that you might find interesting.

By the way, I don't think you are pushing SQLite to its limits 15 columns/ 1000 entries is not that huge!

Answer 3

I've provided an answer to a similar question here. There are details of soft limits and size limits for the table. As far as @Amokrane answer, you'll also need to be aware of limitations not imposed by SQLite, but by android. 50mb is the current maximum app size and there are issues with accessing large datasets on device. Take a look at that answer.
