Take your time.
Take pictures if you want/can to remember how things were before you dismantled them.
String around the oil pickup tube bolt is a nice trick, also works with sock/rag/towel in the oil pan.
I wish there was a perfect solution for holding up the lifters, but I've never read anything but the $80 tool working 100%, that being said, its nice to have a camera to see if any lifters are hanging too low in the nerveracking event that your cam gets hung up on something.
Other than that the double spring changing tool from Crane is nice to have, i sprung for that, as I'm going to have to replace my springs in so many miles anyway, why not make it easier in the future and now.

You can do it by moving the whole thing with pipes on, out of the way but if you pry too hard, you can kink a line and discarge it any ways.
If $$ is not a big issues, to discharge is a good idea so not to bend anything.

Some have had bad luck and will never use wooden dowels again. Some use the russian roulette method and have no trouble. You can use what you want. I'm saying I have the tools for rent to anyone who wants them.
I like real tools that dont splinter or break. The rods are also bevelled on one side. They arent round. I suspect this would have helped Cashss99 when he had homeade rods and had to get a wooden dowel to finish. He tried making his own rods and it wouldnt go all the way in. He got lucky and had the wooden one work for him.
I've never heard of putting pushrods on the spark plug hole?? Pushrods are skinnier than the spark plug hole. Is that supposed to keep the pressure in the cylinder? Some also dont use anything to hold the valves up. All kinds of ways to "cheat" but when cheating goes bad its a giant PIA compared to doing it right.
Its up to you.

right i thought that was how it was explained to me before to but thats why i wanted to get more advice on whta that really meant....isnt tha wher you get tdc do certain cylinders then 90* and do more cylinders and then 90* and so on?? not to clear on that method

to put the crank pulley back on, pick up one of the tools that 918hawk sells. send him a PM and he can get you some pics. Worked great for me, made putting the crank pulley back on a breeze. As for holding up the lifters, i used the $90 JPR tool. I had a ton of "thunder bucks" from thunder racing so it only ended up costing my like $25. It worked great though.
