bellhousing alignment and other q's

Getting ready to mate the bell/tranny to my 318 this weekend. Have a few q's:
1) have a roller pilot bushing - do I tap it all the way into the crank? Out of curiosity - how do you remove it if/when it goes bad?
2) Stock early a-body v8 (small) clutch bellhousing - is it recommended to center it or do you just bolt and go? A friend helped me align a Lakewood bell a while ago on my chevy but i don't remember how we did it! :)
3) Can someone please post a pic on how the fork/thrust bearing attach or provide a link?

thanks for the help!
