To earn a pouch, you need charms. Making pouches is where a majority of experience comes out of summoning. Charms can be gotten from monsters (slaying is among the best methods of getting charms). You'll also require blank pouches, shards, and a secondary ingredient. Shards and pouches can be bought from the man you began Wolf Whistle with in Taverly. To learn what secondary ingredient you want, check the summoning guide and refer to what pouch your making. Making the pouches is sort of RuneScape gold like herblore, just you want to do it in an obelisk rather than at any bank booth you desire. You need supplies, and you make them. Hope that cleared up summoning for you.

Having a team you are going to want to get 100+ combat with 75+ Attack and 80+ Strength minimum, Plus 75 or greater defence so that you're not sat there eating the entire time. Get 70 Prayer and piety, 43 prayer will not cut it. Get 52 Summoning for a Terrorbird at LEAST, or even 67 or whatever for a War Tortoise/68 for a Bunyip. Raise your magic (to maybe 70) for getting there and to assist contrary to being Mage-raped.

As for armour and weapons in that level I'd recommend something precise and hard hitting (use a whip and you will just be a waste of space for the group - you'd never strike ). Maybe this: Bandos Godsword (Use the Specific Attack to lower Defence). Helm of all Neitiznot. Amulet of Fury (or Glory in case you can not afford that). Woodcutting Skillcape. 1 Zamorak Arrow (stops enemies attacking you during killcount). Dragon Boots or Buy RS gold Climbing Boots (If you have to walk there - make sure these are the 75K ones, they supply a +2 Strength Bonus). Great luck, you have got a great deal of training to perform.
