G'day Mark,
Welcome to the forums mate.. In answer to your questions....
1. What Oil? - MAny brands to choose from.. Shell Helix Ultra, Castrol Formula R Synthetic [is what i'm running], Penrite.. yada yada yada.. How deep is your pocket?
2. What Grade/Viscosity?? - 5W-40 is the usual choice here for AGT competitors.. I run 10W-60 for that little bit extra protection.. It's a little thicker on startup, but once it's warm it's very similar performance wise and offers better protection..
3 & 4. Tappet noise? - yes it's the lifters.. a good sign to change your oil as soon as possible!
Regards
Adam
