If I look at the file's bytes I can definately see some of the function names in there. Is there any tool that will list them for me? Maybe even their parameters too?

This should print all defined symbols within your object file or library.
nm -C --defined-only file.o
nm has quite a lot of options that you could use to filter out the symbols like -g for displaying only global symbols, -l for printing the line number (if you had used gcc -g to enable debug symbols) and so on.
If you have an ELF format binary (looks to be your case), you could also use readelf
readelf -Ws file.o
The column number 8 in this output contains the symbol name which is of interest. You could use c++filt to demangle the name:
readelf -Ws file.o | awk '{print $8}' | c++filt
