I'm learing how to design PCBs with Eagle.

More or less now I begin to understand Eagle and can create PCBs, new libraries etc.
I've done a home-made single layer PCB and as a next step I would like to order a slightly more complex circuit (with the free Eagle version, two layers).

I have the book "Build your own PCB" by Al Williams and there are some guidelines to prepare Gerber files (.cmp, .sol, .plc...). However, I also downloaded the SparkFun CAM file and it generates a totally different set of filename extensions. So right now I'm really confused !

My questions are:
1-Is there a set of standard gerber files ?
2-How do you review and verify your files before submitting them ?
3-Is someone out there accepting Eagle files ? (In case this makes sense)

If someone who has ordered PCBs could help me I would really appreciate it.

Thanks,

1-Is there a set of standard gerber files ?

No...yes...kind of. It's common for Eagle users to generate:

.cmp: top-side copper ("component" side, hence cmp)
.sol: bottom-side copper ('solder" side, hence sol)
.plc: top-side silkscreen (PLacement on Component side)
.pls: bottom-side silkscreen (PLacement on Solder side)

etc.

But there is no standard for what the files are called. Just be clear about it when you submit your files.

2-How do you review and verify your files before submitting them ?

Use a Gerber file viewer like GC-Prevue, ViewMate, or gerbv for Linux/Mac systems.

3-Is someone out there accepting Eagle files ? (In case this makes sense)

Yes...but don't do it. You are counting on someone else interpreting your board and generating what they think is the CAM data. Proceed as you suggest above: learn to generate the CAM data, verify it (twice) using a Gerber viewer, then submit that. You will have much fewer surprises.

Yes.  Laen at dorkbot will accept eagle files.  You'll have to make sure your silkscreen info is correct, but that's the only catch I had.  I've sent in 4 breakout board designs, all came out great.

dorkbop pdx is pretty good. I once contacted someone else and they told me they only accept protel 99 file. Darn the cheap price comes from not upgrading I guess.
