I will be very grateful for any advise or reference on the following.

1- How much is known about infinite families in ${_2\pi_*^s}$, the $2$-component of the stable homotopy ring? 

2- How much is known about possible geometric construction of any of these families?!

I like to know about known constructions of such families by geometric methods. The geometric constructions that I am interested in are 

(i) factoring an element of $f\in{_2\pi_*^s}$ through some finite dimensional complexes. The $\eta_i$ elements of Mahowald family are constructed in such a way. 
Also representing $f$ in terms of triple or higher Toda bracket will lead to such a factorisation, not necessarily unique. 

(ii) constructing elements using homotopy operations arising as described by Bruner. For instance, Bruner's $\tau_i$ family is constructed using$\cup_1$ operation as described by Bruner.

I doubt if there is any structural result on the existence of such families; I presume whether or not if there exist finite number of such families is not known?! and if anything known would be a collection of latest results, something like what we find in Ravenel's Green book (do not know if a more updated reference exists!).
