I don't recall if TrueAncestor has a thing for SPRX files, but E/S/S/S/E Resigner does. Use the option to resign a sprx file, and half-way through the decrypted prx file will be present in the resigned sprx files folder. Grab that file, and treat it like a normal decrypted elf file and use fself to convert it to DEX.
If you really do need dex to cex, same process. Treat it like a normal EBOOT.BIN. The only time you need to do anything special is when you decrypt it from a game's disk for the 1st time, and then you can freely do the same encrypt/decrypt stuff you would like an EBOOt.BIN from there.
