IPC-7351 for SMD components... Free viewer with most footprints you'll ever require.
IPC-7351 Land Pattern Calculator and Tools
Havn't put much up about PTH as there pretty common with most packages and relitively easy.
I'm do some funky boards 14 plus layers, HDI, controlled impedance RF etc but also normal boards 2 -8 layer, and lots of power supplies, cos everything has a PSU, and then point of load.
Post your schematic we'll all have a look and help. The layout would be best done by someone who uses a free package, then you can play with the data and that way youll learn.
I2S and digital signal path - in-line resistors?
If your fealing machocistic there is a list of PCB related sites (and a text file version) that I use for people asking about the basics of PCB designthese days.
