You have two questions here.
1. Text extrusion. At present the Substance model graph, used for procedural modelling, does not have a text node. You could use Stager or a 3D app for text extrusion.
2. The curve node you show, which is in the normal Substance Graph used to make materials is for adjusting the levels in an image fed to its input. It is more powerful than a simple levels adjustment as it allows several control points to be set - each describing how the output will change in comparison to the input level. So for example an S shaped curve can be used to increase contrast in the mid tones without clipping the dark and light ends.
Substance Designer started as a procedural material design tool. Only recently has the procedural modelling graph been added. You might want to look at some basic tutorials to get you going :
