For certain, do the practice holes. If you drill the hole crooked, then your tapped hole will be crooked. Use a small square to give your eyes a line to compare against, have someone help watch to keep the bit straight, for cast iron I like to use any EP2 grease as a cleaner / lubricant on the tap. Push some into the bore your tapping and smear some onto the tap. It'll push aside the chips and help carry them out, wipe and replace it often.

Use the corect drill bit ( it should be part of your kit ) and take your time. Cast is usually easy to thread but very dirty! Another reason to use the grease, it helps contain the dirt / dust from machining , when drilling, use a vacuum to remove the dust, cover any parts of the motor that may be open.

Again, take your time and have fun with it.. after you do a couple holes, you'll be confident to do the real one.
