Well......this is one of those questions that is kind of hard to answer since no-one has any idea what you want to use your gun for.

Do you see much trigger creep? You shouldn't as Shadows come with shorter-than-usual hammer hooks. If you still wanna install comp. hammer, you are kinda 50/50, some require disconnector fitting while others don't. Safety-to-sear fitting will be required thou as comp hammer bed is higher and thus rotates sear forward and pushes sear against safety (left). Some people like fitting sear to safety, I fit safety to sear, it's easier and quicker and does same thing.
For softer hand loads you can use 11# to 14# recoil spring, one that will allow brass to eject 6-10 feet away from you, not dropping brass onto your feet or launching it to another Province. Main spring can be as low as 13# but you may experience ocassional light strike, especially on new gun or/and with CCI primers; 15# is safe bet. You can go with 13# main and extended firing pin for reliable ignition too.

Fwiw, replacing the stock 18# mainspring with a 13# spring is very easy to do, very cheap, and improves an already good trigger. Since I use mine for target shooting, the noticeably lighter trigger is a real plus. Well worth doing, IMO.
I have a 15 lb mainspring in my CZ 75B and it ignites all primers reliably. In conjunction with a stock hammer with the hooks stoned to get rid of hammer cam, the single action trigger is about 3 lbs. I prefer not to use a lighter mainspring because I don't want to limit myself to Federal primers (which aren't always easy to find) and the pull weight is good enough for me with the 15 lb spring.
Do a search on all my old post regarding the Shadow and you will find all you need regarding comp hammer and spring swap including some youtube video links.
I changed all 3 and love it... now I have the Kadet 2 .22cal conversion kit... what a dream combo, one trigger system... two calibers. My trigger finger's muscle memory will be perfectly honed come the 2011 IPSC season. I can shoot 500 rds from my .22cal Shadow for $25.00
That's right folk... I'd rather be at the range capping off a 1000 rds and practicing my skills with my .22cal Shadow and CED 7000 then at home dry firing.
Well, I've had no issues with the 13# mainspring igniting CCI small pistol primers, and these are said to be harder than most. Touch wood, I guess.
Loader, I use mine for 50m target shooting, and it works quite well for that, using a 6 o'clock hold. Ok, 5:30, in my case.

In that case I wouldn't bother changing anything on the gun. Just shoot it. The single action trigger on the Shadow is excellent right out of the box. However if you plan to do some double action shooting then changing the mainspring out for a 13# is a good investment. It will lighten and smooth the DA pull noticeably.
Lighter recoil springs are intended to tune the recoil to the load for competition purposes. Not needed in your case.
Other than that I would just go for it. Shoot it up

The competition hammer installed on the 85 Combat gives you the same trigger as the Shadow. Like a previous poster stated the trigger system is identical on both guns.
Take Care
