I'm miles away, so can't help in terms of partners etc, but
- Sport climbing is where there are permanent bolts in the rock which you clip the rope to as you climb up.
- Trad climbing is where you take lots of bits of gear up with you which you place in cracks as you climb, clipping the rope to those. If you fall off, you hope that you placed the gear well and that it won't rip out as it takes the force of the fall (if it's been placed well, it won't). Then your partner follows you up the climb and removes all the gear - it's expensive, you'll want it back.
There's more to it than that, but that's the basic difference. I don't know how much sport climbing there is near you, I suspect not much in the low grades. The climbing on sea cliffs is almost all trad I think - it's very exciting and you definitely need a bit of experience and to know what you're doing. There's loads of info for beginners on the internet, search the articles on here for a start. It might be worth going on a weekend course to learn the basics, if you're not successful in meeting someone who can teach you on here.
Good luck. Getting into climbing is a great idea. Lots of amazing experiences to be had, for a whole lifetime.
