As for sealer, I'm a big proponent of shellac (dewaxed). It goes on easily, dries quickly and is compatible with just about any topcoat. (certainly with any lacquers and enamels I've tried)
My mantra is becoming "when in doubt - shellac it". Whether you mix your own or buy it premixed, as long as it's dewaxed.
Shellac can also be used to grain fill using a slurry method with pumice, but I haven't tried that yet. (I have used the slurry method with Tru Oil, but that's a whole 'nother thread)
The process I would do is: grain fill > shellac > primer > base coat > clear coat.
Of course, some acrylic base coats will buff up just fine without the clear, but it depends on the product.
