i just bought a 2008 Impreza Outback sport 5 speed manual and I'm not sure what i should be upgrading first?

the car has 200,000 miles on it and I'm replacing the clutch, master cylinder, and slave cylinder right of the bat. I want to find some suspension eventually, but I don't know what is worth it should go for a longer travel shock and what kind of damper I should get. I have already ordered a 1-inch aluminum spacer lift kit to rase it up a bit. And for someone starting rally is it worth it to go after more power. Tires are my main area that I don't know much about other than what the treed patterns look like, but I don't know the sufficient names or part numbers.
