Attic insulation and air flow

My house is a 1920's craftsman bungalow in northern California. I am insulating my attic with R-38 kraft faced insulation. I notice no soffit vents from the exterior or interior of the attic. It does, however, have several small gable vents in the front and rear wall of the attic. My questions is:

Can I install the insulation all the way to the edge of the attic floor or do I need to install baffles to allow proper air flow?

Craftman style homes usually have their rafter ends exposed as part of their design, so there is no way for you to have eave or soffit vents. Therefore the baffles are not necessary. If the gable vents are at different heights in the attic, it might provide you with free venting. The high vents allows heat to flow out of the attic and the lower vent will allow air to enter the attic to replace the amount of air that left. So it's not absolutely necessary to have vents in your eaves, just vents that are lower than other vents in the attic.
