NEED some advice on lowering project

[RWJJR]

Ive had 84 a year trying to decide what to do with it,now Ive decided on a new engine and mild drop.Ive done alot of research here and decided for now my best bet is a 2/3 with cut coils and shackles W/ overload spring removed.I have a couple questions.

1.I plan on replacing the shocks all the way around (still has factory),will some OEM replacements be ok with this mild of drop?or should I go with drop shocks?also I believe the shocks will need to be shorter in the front and longer in the rear,is this correct?If so I may try to match up some with different measurments.

2.Will I be able to get the front end aligned without any major problems.

Thanks and please give any input you think might be helpful.
