A few recommendations

1. LEDs are nice. I recommend you get manual print out light sheet. I count all bulbs on sheet. 555 are the ones that do not have a metal base. 44 have metal base but are replaced by 47. Flashers are 906. Then you have to count bulbs under plastic and back glass. A rule of thumb back glass should have frosted bulbs. The playfield I prefer warm bulbs. You can decide if you want to order color bulb for to acent things or go crazy with coler. I high recommend your order this way rather than buy kit. A lot cheaper. I do not recommend LEDs for flashers or pop bumpers. After you know what you want I recommend pinball life but there are other online stores.

2. I never bothered

3. I would recommend you Novus 1 2 and 3. Cleaners. do not use water. I like to wax mine as well. I use millwax many do not recommend.

4. Look at manual and order parts. Marco Specilaties has a great website and make it easy. Dont make a mistake as really there are no returns. Order a flipper rebuild kit. Since this is your first machine replace everything rather the debug. It is most likely a bad spring, sleeve issue or flipper gummed up some place.

Enjoy working on machine that is half the fun of owning it
