To make a pouch, you need charms. The process of making pouches can be described as where a majority of experience comes in RS gold summoning. Charms can be obtained from monsters (slaying is among the best ways to get charms). You'll also require blank pouches for shards, pouches, and an additional ingredient. The pouches and shards can be purchased from the player you started Wolf Whistle with in Taverly. To find out which secondary ingredient you require, refer to the summoning instructions and look up the pouch you are making.
Making the pouches is kind of like herblore. However, you must do it at an obelisk , rather than in any bank booth you want. You will require supplies before you create them. Hope that cleared up summoning for you.
As a player, you'll want to score 100+ in combat with 75+ Attack and 80+ Strength with a 75 or greater defense, so you're no longer in a restaurant eating all day. Take 70 prayers and piety and 43 prayer will not be enough. Get 52 Summoning for the Terrorbird at a minimum, even If not 67, or something else to get a War Tortoise or 68 for a Bunyip. Make sure you raise your magical level (to perhaps 70) in order to reach that goal and to prevent being Mage-raped.
The minimum team stats includes 80 attacking, 75 defense, 75 str, 52 summon, 60 pray, 75 magic for magic def - Those aren't required statistics. Minimum is to be 85/85/85, with 70 prayers as well as 80 magic and possibly some fruitbat. After I put the stats you suggested in zybez's combat calculation, it ended up as 96cb. The cheap OSRS gold minimum is 115cb and the majority of teams will ask for 115cb in order to have chaotics.
