No worries feel free to ask.

You in no way need a $50 set of brushes. Any acrylic paint brush set should work, you can find plenty on Amazon for <$20. I use the Masters Touch brushes from Hobby Lobby you can usually find on sale for about $3-4/brush. Amy Painter has starter sets for ~$11-20 while you can get some cheaper sets as well.

Army Painter(and Vellejo) all have starter sets but you're not really saving that much buying them. Army painter and Vellejo Game color pots are ~$3/bottle, if you're buying one of their sets like the one linked you're still paying that price the only difference is that you're getting a free brush with that. However the down side is that you'll be getting colors that you won't be using. Lets say you take the absolute bare minimum to paint your clones force, grab Army Painter or Vellojo White, black, wolf grey paints and a bottle soft tone wash, that runs you ~$12 at your FLGS or miniature market. For another $9 grab a brown, blue and skin tone to paint Obi-wan. Add in another color for your legion if you don't want plain white clones, and a basic paint brush set like one linked above, and you've got all the paint you need for a basic paint job for about $35.

You can even do the method I originally described for about the same cost, $12 in paintbrushes, $3 1x pot wolf grey for brush on priming, $7.80 apothecary white , $3 1x pot pure white for drybrushing, $3 for your legion color, and $5 for the micron pen; for a total of $33.80.
