Hi Mona!
Glad to see you at least got in!
If the game seems to run slow, it could be a couple of main issues right off the bat.
First, system memory. If you have less then 512MB RAM, you probably want to think of upgrading. I mean heck, 1GB RAM sticks right now are running at $89 so it's not the expensive

Second, your graphics card. Don't downplay this in any machine you use for gaming. More and more developers are utilizing the high-end capabilities found in todays extreme graphic cards, and supposedly in version 1.1 due to be released this month, Second Life will be no exception to this rule. I know people will cringe when I say this, but if you have the funds available, I would go with the high end Nvidia card. Not just to play SL, but to play any online game. The marked improvement you will see all around is more then worth it. Yes, the high-end cards are a bit expensive, but if you are a hard-core gamer (like myself) then you won't be bothered by this

Third, in the game, you might want to go into EDIT, PREFERENCES, DISPLAY, and then lower the settings in there. Settings too high can max a graphic card that isn't high-end. Therefore, lower some of those settings and see how things go.
Anytime you are in the game, the best way to find out about what's going on, is to check the event board in the Getting Started area. Also, you can contact any LINDEN in game and ask them for a copy of today's events card.
Personally I think LL should make a function for thier admins and send out this notecard on a daily basis, or just automatically deposit it into our notecard folder. Another way would be to have an automated system, much like the Message of the Day, and load the current events for the day into that, where people can access it from anywhere they are.
Either way, that's how to find out about what's going on and where. Also, there are places that people naturally gravitate towards. Probably one of my most favorite is JOAN'S in Kissling. It's a great atmosphere and a wonderful surrounding, and I can't think of two better people to be host to an afternoon of fun. Of course, you can always look me up, and if I'm in-game, I would be happy to entertain you at the Cabin in slate. It's a nice quiet part of the world where we can just sit and relax and I can answer any further questions you might have.
No matter what you do though, remember to have fun!
