New 1964 owner with many questions

Hey guys, I bought this ‘64 dart slant six. It was not running, but I got it running, still needs voltage regulator (not charging). Questions I have for now are;
1. No power drum brakes are they adequate for a daily driver?
2. Is it worth buying JEGS steel brake lines vs making your own (my thought is I don’t have to buy tools )
3. Is there any source to buy stainless trims, taillights, etc.
4. Is Borg Warner electronic ignition kit EI-6 worth buying? Is there better options without spending hundreds of dollars
5. Does anyone makes complete exhaust for slant 6?
Thank you for looking!
