Yes, take out the radiator, no, leave the grill. You didn't say manual or auto, or if you intend to leave the trans in. Unless you have other reasons to pull the trans, leave it in but support it. If its a manual, be very careful when reinstalling. The inbound alignment needs to be carefully watched. If you "force" it back together, the trans nose cone can fracture or you can wipeout the clutch release bearing and/or the pilot bearing.
If you have any questions, holler....I'm a little south of ya.
