How to design typography in PSD site layout?

Question

HTML

First, I made a site layout. I have h1, h2 and a lot of h3 tags. I want to change the font and color for all h3 tags at the same time, maybe there is some kind of plugin, or best practices?
Second, how not to make a mistake yourself and not make different top and bottom indents for the same headings?
Third, is it necessary to put all the typography in one layer so that the layout designer typesets the entire typography file at once?

1. You can select the Text tool , then select all the desired text layers and simply change their parameters.
2. In the new versions of Photoshop (CC 14), indent indicators from different elements have been added. If you are sitting on the old version, then only manually measure and align.
3. To whom it is more convenient. Some typeset in blocks, some on the main semantic elements.
