Application Question for a Suspension Rebuild

So, I am the original owner of a still young 2003 4x4 3.4L V6 Xtra SR5 Tacoma (all stock) with 140k miles all driven in New England. This is my DD athough i do some driving on dirt roads up here in maine and in NH when i go into the backcountry but only on the weekends. I am thinking of doing the following suspension replacement:

Upfront:
Camburg 2.5" coilovers (really sway-a-way race runners 56000-108) - run a 2 to 2.5" lift in the front
Camburg 1" uni-ball UCAs

Rear:
Bilstein 5100
New leaf springs (was thinking of finding a local spring shop in new england) with a max lift of 1.5" - i am still trying to figure these out.

Concerns/Questions:
1) Salt - I am concerned with salt build up on/in the uniballs and also corrosion of the anodized aluminum coil over parts (especially the threaded adjusting collars) - any feed back on this?
2) It seems that the sway-a-ways use 650lb coils in the front and i am concerned with these being too stiff. Should I look into other brands that have lower spring weights (I know King, Icon, and Fox all do). I would like to get new bumpers but those would not be right now maybe in 1yr.
3) Since the coil on the sway-a-ways are closer to the LCA, it seems like i might get some interference with the banjo/bolt for the brake calipers - anyone ever run into this?
4) I would like to replace the leaf packs since they are almost flat (so I dont think AAL will last long) and want something beefier than stock but i do not want more than a 1.5" lift. I do haul equipment, fire wood and the occasional 1100lb granite mooring block (I think this may have did the springs in over time). This is also my DD so I take trips for work all over new england. Alcan and Deavers seem geared more towards offroad and was thinking of finding a local spring shop. Can anyone suggest any in NE or recommend some spring characteristics that I could order though a local shop

Any help/suggestions would be great. Also feel free to scap all my picks and suggest different line ups.

Thanks
