I started out drawing the traces by hand too, in AutoCAD etc before going the Eagle/PCBGCode route. One other tremendously valuable resource is:
http://thinktink.com/, this is the parent company of
http://precisebits.com. There is a lot of information on the Think & Tinker site, it is well worth reading over several times.
One nice thing they offer is:
http://www.thinktink.com/cgi-bin/carbide.cgi?page=drillset&step=20&start=0These are a sets of solid carbide drills in most common sizes needed for through hole, SMT, and metric equivalent (in that order on page). When I got started milling PCBs I didn't have any idea what the best sizes of drills to have on hand I wanted to save some money by taking advantage of the Qty 10 of a single type bit discount but did not want to buy a bunch of bits that I would wind up not using. So the kits appeal to my 'frugal' side. I was talking to them last night about coming up with a 'starter' set that includes a couple of 60 deg trace isolation bits. I think we figured out what would work in such a kit so I plan to have all the sets including the new starter kit available on my website,
www.soigeneris.com, in a few weeks.
Don't read the above as a big sales pitch, it's not. I've learned a lot from my 'Mach' friends here over the years and if I can help a few save some of their hard earned $ then that is great.
