to SHIFT KIT or not to SHIFT KIT??

Just picked up a '95 E4OD (RWD) "Lightning" tranny with only 33K miles on it. (Will be mated to '95 5.8 using factory harness/PCM in a '52 F3.)
I know that "ideally" a shift kit is always a good thing, but I'm weighing the pros/cons based on the following:
1) $$ (this is a budget build)
2) this tranny is low-miles and in great shape (reportedly) as-is
3) I've never torn into an AT before and am a bit reluctant (i.e. nervous) with sooo many parts involved!
4) impatience : I've yet to fire up the rebuilt motor and am anxious to just replace the filter (which I have ready to go) and fill it with fluid (16 qts?) so I can bolt up the starter and call it good!
5) I'm not building a race truck, tho will see some "spirited" driving.
Any insight appreciated.
If you dont want add the extra work and are a bit impatient with getting this project running. I would just install the transmission as it is and get the vehicle moving and adjust later if needed.
