All new lenses I have bought come with a lens cap.
I can't say about a second lens, when I don't know what first lens you will get.
But I would recommend that you use the first lens for a least a month before thinking a bout a second lens.
By that time you will know what type of lens you need.
The UV filter is normally used as physical protection for the lens.
Much like an insurance policy.
You may or may not need it.
If you use the lens cap when not taking pictures you can get by without a UV filter.

I am a teenager who wants to , with the help of dad (who is photography fanatic), to buy a digital SLR. I have the SONY Alpha DSLR-A230 in mind because of its good review on cnet and its price. I have a budget of 600 dollars. I plan to use the camera on school trips, family get-togethers, and outdoor scenery type things. I was wondering if I should get a second zoom lens, a UV filter, and a lens cap. If anyone has any sugestions or other recommendations feel free to leave a comment. Thanks.
