You don't need to, and shouldn't use load when debugging
an unix like process.  "load" only makes sense for embedded
debugging --- it copies the program straight into the target's
memory.  When debugging on linux, or full blown OS, you want to 
create a new process, and that's what "run" does.

That's good.  After that, tell gdbserver which program to run
with "(gdb) set remote exec-file myprog".  Then you can just
type "run" to launch a new process, just like you were
debugging natively.

If you instead start gdbserver like so:

 $ gdbserver :9999 myprog

gdbserver will start the myprog program for you; This means
there'll already by a process running when you connect with
gdb.

Don't.

To the debuggee/`inferior process' memory.  It doesn't make much sense
to use "load" when debugging a unix-like process.
