[pygame] Newbie needs help, what's the most efficient (or easiest) way to do this?

["Charles Christie" <sonicbhoc@xxxxxxxxx>]

Hey, I am making a typing game in Python using pygame. I have finally hit a
roadblock, and I think I'm toast. I started this game as my senior project,
and I need to have something to at least demonstrate by June.

I think I screwed myself on this one. I thought I knew a reasonable amount of
programming, but absolutely none of it is coming in handy. I had to ask for
help to get what I have now, and now I've hit a road block.

So, what I need is:

A. To find a way to feed multiple strings into the program. As in, when you
finish one string, instead of starting it over again you instead go to
the next word in the list, which I guessed should be an array of
strings. I'm probably wrong, though. What's the most efficient (or
easiest) way to do this?

B. Two timers, a combo timer and a word timer that count backwards. I
know I can figure out how to do these myself, though.

The code I have so far looks like this:
