All the required measurements are on the first page of the data sheet. Those are all the dimensions you need to create a footprint - just copy the footprint from another part (like a 4 pin dip), and modify the spacing accordingly. Ditto for the symbol.
Honestly, I use Protel because I can get work done with it. It *IS* boring, tedious, and at times I'd like nothing better than to reformat the machine and nuke it - and I get paid $xx an hour to do stuff with it which makes up for it. Now, suggestions, hints, general knowledge, those are all good things and easy freebies, but when dealing with grunt work (and making symbols and footprints *is* grunt work), I'm going to be a skinflint and refuse to do.
And if you want another reason, making footprints and symbols isn't cut and dry. Depending on who you have manufacture your board, you'll need to have a lot of knowledge about the board - available hole sizes, plated hole sizes, inner layer keepouts, solder mask pullbacks, etc. Ditto with the symbols - a rectangle with 4 pins is sufficient for my design purposes, but if you ever show the schematic to anyone else, you'll probably get an earful, followed by an endless stream of questions.
