There are a number of ways to do this. For example
{f[#[[1]]],g[#[[2]]]}&/@data1
or equivalently
{f[First[#]],g[Last[#]]}&/@data1
or
MapThread[{f[#1],g[#2]}&,Transpose[data1]]
I am sure there are many other ways I haven't thought of yet as well. Mathematica provides a fairly rich set of tools to manipulate lists.
