Hey guys, thanks for the encouraging words and advice. fender3x, thanks for all of that info, I will take a look at the Platina shellac.

Right now, I'm planning to use Aqua Coat grain filler, especially since you recommend it and I already bought it

For the top coat, I plan to use Saman water based varnish. I do have a nice synthetic hair brush, so I will try that instead of the foam brush.
