Probably the best way to learn to mod with ECWolf would be to make a few mods for ZDoom. There's a lot more information in the Doom community and a good chunk of it is transferable. Grab some Doom mods and look at the contents in Slade and you should be able to see some patterns.
With that said, to replace the sounds you would provide files with the same name as to what's assigned to the vanilla data. You can find the names in ecwolf.pk3 in the *map.txt files for example
here. Things get a little more tricky with the sounds that are only AdLib/PC Speaker as you will need to redefine the sound in SNDINFO. There's a sndinfo.txt which provides mappings from logical names to sound names. You would just need to have a sndinfo file which has the logical name you want to replace and then the name of the sound file.
For weapon sprites they work just like Doom. If you want classic Wolf3D scale sprites then you will need to use the TEXTURES lump to scale them 2.5x.
