Those other weapons look interesting, when will I learn those?

The emphasis in Shinto Muso ryu is on the Jo/staff and Tachi/sword.  The sword is at the heart of almost all classical Japanese martial arts.  Every time we do a Jo kata, there is a corresponding sword form, and we put great emphasis on using the sword properly.  The Jo itself is also frequently used as if were a sword.  For these reasons, some people have called Shinto Muso Ryu a school of the Jo and Tachi.  From the beginning you are learning both Jo and Tachi.   The Kata that specifically train the other weapons (Kenjutsu, Tanjo, Kusarigama, Jutte) are taught after a solid foundation with the Jo has been established, which usually takes several years.
