Tru-oil, staining, and grain-filling

[Bklynn Blues]

If I use tru-oil on an open-grained wood such as ash or mahogany is it necessary to fill the grain, and if so, can I use a water-based grain filler?

Also, can I use water-based dye stains under tru-oil, or should I go with an alcohol-based dye stain? And should I seal the stain with shellac before before applying tru-oil, or is that a nitrocellulose procedure?

Thanks in advance for your replies.
