Importance of Access to Scrolls?

[andepans]

Rolling a human ice savant in a few days and I would like some advice on how useful keeping my main hand free to use heal scrolls might be. So here are my questions to all of you capped fleshy sorcs out there:

1) How important is easy access to heal scrolls?
2) Is a heal amp weapon worth the slot?

Here's what I've come up with for my gear (mostly stuff I already have, suggestions welcomed.) The whole setup would be easier if I could rely on using the Staff's epic slots most of the time, but I'm not real happy slotting important bonuses in an item I'll be swapping out.

weapons - heal scrolls / GS (Conc. opp, 20, 30 amp) / green blade / Lorrik's Shield / epic staff of arcane power (nothing slotted)
goggles - GS (45hp, Conc. Opp.)
helm - epic frost (GFL)
trinket - litany/eardweller/bauble
necklace - torc
cloak - epic envenomed (toughness)
belt - heavy fort w/ guild slot hp
gloves - GS (Wiz6, 150 SP, 6 umd)
boots - epic corrosion (+1 CHA/ +6 DEX depending on ring setup, good luck)
bracers - bracers of madness
armor - epic diabolist (1 CON, -15% ASF)
ring1 - tod 2 CHA
ring2 - tod 2 CON

edit: Just to clarify - having 40 UMD is not the issue here. Mostly asking about the need to quickly access heal scrolls midfight in difficult quests/raids.
