Just a tip about EAGLE pad size:
Use DRC to alter the pad size AFTER you have done the layout. Click DRC icon then in sizes tab (or restring tab? Sorry I forget which one) increase minimum size to about 17-20 mil. Click apply to see the magic happens.
I'm curious about KiCad, so I'm downloading it now. Thanks Phatt for mentioning it. :tu:
For 6 pcs production I suggest you try the hand drawing method or the toner transfer method (Is this the right term?). It's fairly easy for a newbie like me, and FAR cheaper than ordering. Try it and you won't order anymore. Just remember about the safety factor: safety googles, rubber gloves, air circulation, waste treatment.
Note:
Happy etching!!! :tu:
Edit: After a quick look, IMHO your traces are too thin. Try 0.05". As for the pad size, try my tips. It's only a few clicks away. Try this tutorial to add a ground plane: http://www.muzique.com/schem/eagle.htm. At least it will speed up the etching process. You also have untraced connection between R9 and R7 (See that yellow line?). I suggest to bevel / chamfer or round / fillet your traces for better electron flow. There are buttons to activate them when tracing. They're just above the drawing panel.
For those who are frustrated with EAGLE's component library (like me), try Gauss Markov's library: http://gaussmarkov.net/wordpress/tools/software/eagle/eagle-2-libraries/. A lot easier to use.

Hope that helps.

Note:
- If you don't have laser printer or magazine paper, you can print your layout on ordinary paper then photocopy it on the thinnest paper available (60 g/m2 will do). I use XEROX photocopier with darkest setting for best result.
- Always remember to balance between your copper trace and the spacing between traces for easy transfer. I use 0.05" for copper trace width.
