GSF600 Bandit maintenance (brake drive chain)

Hello have my brake pads replaced today in the front with new ones from Brembo Carbon Ceramicbelag…. I have a question regarding my brake fluid… how do I do this so best the change? have searched for in the forum but found nothing… And regarding my drive chain wheel and my chain sniper I have now bought new ones that want to change now I need a motorcycle lifter or can I do it without doing so only with tools? Is there a very cheap workshop and good i n Munich? That would be the emergency solution but of course prefer it itself… Thanks in advance
