Almost every Monster Drops Gold Charms but you can receive multiple charms from the level 111 Giant Rock Crab in the Chaos Tunnels.
When I trained range on fire giants i got like 100 blue charms or more their not likely to appear though that's just one of the monsters that drop them try going to a runescape help site and type in monsters that do drop blue charms.
it depends what kind of charms you use and what familiars you summon. Also, once you do the quest to start the summoning skill you get enough xp to go straight to level 4.
There is no such thing as Blue Shards, however if you meant "Blue Charms" I have provided you with a link below that should provide the answer(s) that you seek.
