In this paper, we establish connections between the first extensions ofsimple modules and certain filtrations of of standard modules in the setting ofgraded Hecke algebras. The filtrations involved are radical filtrations andJantzen filtrations. Our approach involves the use of information from theLanglands classification as well as some deeper understanding on some structureof some modules. Such module arises from the image of a Knapp-Stein typeintertwining operator and is a quotient of a generalized standard module. Alongthe way, we also deduce some results on the blocks for finite-dimensionalmodules of graded Hecke alebras.  As an application, we compute the Ext-groups for irreducible modules in ablock for the graded Hecke algebra of type $C_3$, assuming the truth of aversion of Jantzen conjecture.
