Gordy,
I've just posted to your other thread about the gun set up, so I won't repeat myself on this one.
Some form of pellet lube might be worth using, but only you can prove/disprove whether it works for you.
Don't bother with a cleaning kit, I doubt you'll need one - you could make your own pull-through from a piece of strong fishing line, other than that theres not much needs specialist gear.
Being a gun with synthetic furnature, you won't need anything fancy, clean mud off with a damp cloth and an occaisional wipe of the metal bits with an oily rag should be fine. If you find that the buddy bottle cover squeeks when moved, you could rub some unperfumed talcum powder into it, to take the "grippiness" out of the rubber
The manual recommends synthetic grease for magazine O-rings, there are many suppliers around for these lubricants so do as you feel. Best advice as far as any form of lubrication goes, too little and it will wear out; too much and it will collect dust, turn into grinding paste and it'll wear out; get the right amount on, in the right place, and it will last for many years.
Scope cleaning, get a glasses cleaning cloth from the opticians or a camera brush from the photographers.
Happy shooting
