Bolt in means you don't have to change anything else when you install it.

At the risk of chanting the mantra, you really should get a manual, Haynes, Clymer or Factory will do but get one!!
But, in answer to your questions. Each jug must be at TDC compression (both valves closed) before dismantling pushrods.
You have to take the keepers out of the pushrod tubes and collapse them before cutting the pushrods with a bolt cutter (I don't ever use or recommend adjustable pushrods) but you want to so that's how you do it.
You don't need a puller to remove the cam but you will need a blind hole puller to change the inner cam bearing....even if you have the cageless full-complement bearing I would advise you change it if fitting a new cam as they cost peanuts to buy.
You should get the gear drive pressed off your old cam and onto your new one as they come in many sizes and if you use the original then you know its the right size.

If you have to ask these sorts of questions then you probably don't wanna be pulling your bike apart....sorry but that's the truth of the matter.

(to me) in this instance and obviously doesnt include info. on easy install pushrod installation. I have some experience over the years rebuilding Brit & Jap stuff. New to Harley though as you know.
Its good to get advice from you guys though as it usually is much clearer than in the manual.
Im enjoying the evo partial stripdown and as the motor is sitting on a bench I have good access. Gotta start somewhere!. Bungo

If you have the motor out on a bench I would go ahead and pull the rocker boxes so that you can use the stock push rods.

clearance on last lobe
I had to shave off from the housing an area less than a sixteenth of an inch to get the ev27 cam to turn without hitting the shelf just below the pilot bearing for the cam. Other than making sure your color codes match you should not have problems. If you do not match with color codes on cam gear have the local shop (dealer 25 bucks) press on your old cam gear to new cam.
