The current route I am taking with Wild shape is this -
At 5th level Wild Shape is a daily that lasts for the encounter and this will be limited to the beast form of the spell (like wolverine),
at 7th or 8th it becomes an encounter that lasts the whole encounter(again limited to the form of the power)
at 11th+ it is a standard action that also costs 1 healing surge, you get the healing surge effect at the end of the wild shape.
I have some not-so-complete ways of dealing with the lower level beast form powers
I will be adding some powers for a weapon (oak cudgel/shillelagh, staff, scimitar)
Meaning no offense, but what is it that you are trying to accomplish with this? It seems to me as though you are attempting to turn the 4e druid into the 3.x druid. The problem is that the 4e druid is nowhere on the 3.x druid's level, and these changes only hurt the class.
A mid level 3.x druid could take the form of a Brown Bear and all the corresponding benefits thereof (increased ability score, natural armor, natural attacks, etc). A 4e druid can't take the form of a Brown Bear at all, though he could become a smallish (medium sized) bear. He does not gain anything beyond access to his Beast Form powers (and loses access to his spells in the process). The 3.x Wild Shape was balanced by being unavailable before 5th level, by requiring a standard action to shift, and being limited by the number of times per day it was usable. The 4e Wild Shape, lacking all of the features that made 3.x Wild Shape so good, doesn't require any of the 3.x limitations either.
4e druids are intended to be able to shift gracefully between melee combat (Beast Form) and ranged spellcasting. That is why Wild Shape includes a free shift when exiting Beast Form (to get you out of melee so that you can cast). The 3.x druid never needed such a feature because it had access to the Natural Spell feat (so that you had no need to switch back and forth).
The healing surge idea is somewhat interesting, but it breaks one of the assumptions of 4e; that being that the number of healing surges you can use in a given combat are limited. It seems to me that at level 11 the druid can just Wild Shape back and forth during combat to spend healing surges limited only by how many they have remaining. That said, I think this is the least problematic of the changes you propose.
These changes don't impact druids who want to play purely casters, but cripple beast druids as well as beast/caster hybrids. I'd be honestly surprised if these changes did much more than strongly discourage your players from playing druids (and if that's all you're after, why not simply ban them outright).
Early on, after my group switched from 2nd ed to 3.0, I had a DM who thought that sneak attack looked broken. He ruled that rogues could only get sneak attack damage once per round and additionally had to meet "backstab requirements" that were much harder to attain than flanking. The result was that, after unsuccessfully trying to convince him to undo the house rule, no one played a rogue in his campaign. Ironically, he never had a problem with druids.
