One thing I noticed in BG2 but not certain if it works in BG1 is that when a druid shape changes into a wolf or bear upon altering back into normal form they get back a few hitpoints. I've never tried this in BG1 so I don't know if it works there as well.

May be in BG1, but I must say my druid in IWD did a pretty swelling job being that fire elemental :D

I heard from a friend that Jahiera gets shapeshift at level 7. Also, it's a skill, not a spell, so it wouldn't matter on the scroll pages (kind of answering myself there, but... ).
If you plan on shapeshifting into a wolf, there IS a a cloak that does that for you. Besides, you only want to shapeshift if you have poor stats. My lil' druid got poorer stats as he became a wolf. He even got encumbered. Also, when I make up my mind to not use any magical weapons with a possible exception to some +1 weapons, those claws can be very usefull compared to a simple wooden club.

True, some of the Shapeshifting forms are nice (in BG2, the Avenger kit also allows you to Shapechange into a Sword Spider, Baby Wyvern, and Fire Salamander), but they're still nothing compared to your Druid form. Yes, they're nice--when you're starting out. You don't have any cool armor or weapons yet, your THAC0 isn't that good, etc., so Shapeshifting into a Wolf or something is a step up. But when you're a kickass high-level Druid with an AC of -4 or something, then any form you Shapeshift into is gonna suck compared to your normal form. Come on, here--Black Bear, Brown Bear, Wolf? Those are BG1 enemies; any BG2 character is going to mistake those animals for Twinkies and have them for a quick snack. Not to mention that when you're Shapeshifted, you can't cast spells.
