Hi twobyfour, For limb walks keep ur centre of gravity low use your free hand for gripping the branches as you move along the limb.If you dont feel comfortable you can use the free end of your rope to tie in to another anchor point giving you two ropes to steady yourself.Redirects can also help immensley in allowing you to move out further on the limb.The real key is to keep as much weight as possible on your harness-unless its a sturdy limb capable of holding your weight.
As for quickfdraws-No go mate,all biners need triple action opening gates.A great investment are endless slings,the uses and applications for these really are endless,amazing cheap pieces of equiptment.
I would agree with all that Djvicke1 advised aswell.
Hope that helps mate
Climb safe
