There is a wiki for this game that is quite helpful that I recommend you get familiar with:
http://wiki.project1999.com/.
There is a newbie guide on the wiki, but I personally don't think it's very helpful. But it's something to get started with since you seem like you are quite new. :

Look for the spell bar on your screen somewhere, and just drag the spells from your book to the bar. That's a more intuitive way to mem your spells. Try and make your way to the newbie yard of whatever town you're in to make sure you're actually killing monsters at your level instead of killing random things (make sure you use consider like suggested above).
If you give more details about what character you are and what city you are starting I am sure people could offer you a lot more help. If you pick a popular, high traffic starting area like Freeport, there will be lots of people going in and out who will be willing to help you if you ask. West Freeport also has lots of weak trash mobs for you to kill with high density.
Some other useful commands you might want to know are /who or just / to know who and what zone you are in.
Honestly the best advice I can give you is to just start in freeport, and /ooc that you are new. There are lots of very, very nice people in P99 who would gladly assist you.
