Motorola, ADI and TI all make cheap DSP kits, which come with development
software (usually assembler). Look at the various architectures and decide
which you like. I've got an ADI EZ-Kit (fixed-point 16-bit) and a TI kit
(32-bit floating-point). I prefer the ADI kit, the assembly language is
*much* nicer, and for most applications, fixed-point is fine. You can use a
floating-point library if you really need FP. That's what I do at work, with
the ADI DSP we use.

Unless you are developing your own algorithms, you don't really need to go
into the details of the maths.
