Here is the list of what's new in R 3.3.3 . Since there are 3,137 characters of information, I think it is counterproductive to copy and paste everything here. Take a look at the link to see what has changed.
Define "worth". Depending on your use of the program, even a 1.x version may be useful. In particular, I like to keep all my computer programs updated. This includes R and its packages. The message package "nome_do_pacote" was built under R version 3.3.3 is only warning you that "nome_do_pacote" has been done and tested with the version 3.3.3 of R . There may be a problem if "nome_do_pacote" is used in an earlier version of the program. But there may be no problem at all. It's just a warning.
See answer 2. It is not necessary to reinstall all packages, but it is suggested. Upgraded packages may have bugs fixed, for example.
