I dont know why the Lee site said they werent suitable for levers, I loaded many hundreds of rounds of 30-30 and 45-70 for levers with lee Loaders, the main issue is using brass from the same gun, if you use someone elses brass it may nor fit your chamber unless full length resized. Chamber checking them as fired brass or loaded rounds can alleviate any embarrassing moments. Lyman/Ideal made tap-in full length sizers (they called them shell resizers) with a rod to tap the shell back out if the shells from your gun eventually become too fat to chamber with only neck sizing. I dont recall it being an issue with the Winchester 94 30-30, or Marlin 1895 or Winchester 1886.

Cleaning shells has mainly been wiping them off with a clean cloth for most of my reloading experience. It was maybe 10 or 12 years after I first started reloading that I knew anyone with a vibratory case cleaner, I had some shells fired with black powder cleaned by a friend with a case cleaner, but it was another 15 or 20 years before i got one, and dont use it every time by any means. Im pretty sure one could only wipe the shells off and be fine so long as no corrosion was present. I clean the case lube off with a rag and rubbing alcohol after sizing, so i guess my rifle shells get a little more attention. Most of my reloaded ammo takes on somewhat of a patina look. It doesnt really bother me.
The Lee powder scoops/measures work OK, well enough for basic reloading. Part of this entire question is a compact basic setup, which the scoops do fine. Keep in mind factory loads are loaded by volume, not every charge weighed, it isnt much different as far as consistency if one is careful an follows the directions. If I were thrown back to using them only I wouldnt lose any sleep over it, only its not as quick as a measure that drops charges.
Agree about a better priming tool as has been mentioned, and adding the full Lee powder measure set (scoops) to give more flexibility with various powders and bullet weights and reduced charges. It looks like the set is up to around $20 including shipping.
