If you want somebody to hold your hand while you do it all, gimme a shout.
Honestly, getting the stuff from the Guardian sites isn't that bad - drive around a bit, shoot some stuff, pick up the debris.
Rinse & repeat.
After that, go to one of the big Guardian relic sites and scan tablets for an hour or so and you'll have all you need.
Personally, I'd suggest picking up all the mat's required to unlock the FSD Booster, the Shield Booster, the PDist and the PP.
The SB is a very handy bit of kit for combat ships and the PDist and PP make a good off-the-shelf substitute for engineered modules on new ships.
You're going to be spending a fair bit of time at the Guardian sites, blasting Sentinels (and the scenery) for the mat's, so you might as well take the opportunity to collect a heap of the Guardian Module fragments rather than just the two(?) required for the FSD Booster.
