Need help calculating CR and XP

[Roto]

So I couldn't find a premade template for what I wanted to do to some animals, so I decided to mess around with them manually, but now I need some help figuring out their new CR and how much xp they should be worth.

First off, the bear:
HP: 42
Init +3
Fort +8, Ref +5, Will +2
Str 15, Dex 13, Con 18, Int 4, Wis 12, Cha 3
AC 16, touch 11, flat footed 15
BAB +3; CMB +5 (+9 grapple); CMD 16
Speed 30ft
Melee 2 claws +5 (1d4+2 plus grab), tentacle tongue +6 (1d4+2 plus grab)
Perecption +6, survival +5, swim +12
This bear has lost their mouth and teeth, and it has become unhinged and a long tongue like tentacle now sprouts from their mouth.

The Wolf:
HP: 13
Init +2
Senses: Blind-Sense, Scent
Fort +5, Ref +5, Will -1
Str 10, Dex 15, Con 15, Int 2, Wis 9, Cha 4
AC 16, touch 12, flat-footed 12 (+2 Dex, +4 natural)
Speed 50ft
Base Atk +1; CMB +1; CMD 13 (17 vs. trip)
Melee bite + 1 (1d6 plus trip)
Perception +6, Stealth +6, Survival +1 (+5 scent tracking)
This creature has lost all fur and is covered in a wiry hide. This hide has covered up their eyes making them completely blind. While this makes them tougher, it also makes them slightly weaker.

The Squirrel:
HP: 3
Init +4
Fort +1, Ref +6, Will +1
Str 2, Dex 19, Con 9, Int 2, Wis 12, Cha 8
AC 18, touch 18, flat-footed 14 (+4 Dex, +4 size)
Speed 20ft
Melee bite +8 (1d2–4)
Acrobatics +6, Climb +16, Perception +1
This creature explodes in a cloud of disgusting gasses when When killed, all non psuedonatural creatures in 5ft roll Fort dc10.. if fail than sicken for 1 round.

The Raven:
HP: 3
Init +2
Fort +1, Ref +4, Will +2
Str 2, Dex 15, Con 8, Int 2, Wis 15, Cha 5
AC 14, touch 14, flat-footed 12 (+2 Dex, +2 size)
Base Atk +0; CMB +0; CMD 6
Speed 10 ft., fly 40 ft. (average)
Melee bite +4 (1d6–4)
Fly +6, Perception +6
The body of this raven is dominated by a beak that is far too large for it. (upped damage of the beak)

Thanks for any help provided.

Pulling the Monster Stats by CR table out, we see that:

The Bear
HP 42 puts it at CR 4
Saves are around CR 5
AC is around CR 3
Attack bonus is around CR 3
Avg damage is around CR 3

It's saves are on the high side, but I'd say CR 3 is appropriate for it. The fight may go a bit longer since it has higher than average HP, but it shouldn't kill anyone right out.

The Wolf
HP is between CR ½ and 1
Saves are CR 2
AC is between CR 3 and 4
Attack bonus is appropriate for CR ½
Damage is appropriate for CR ½

A party of level 1 characters would miss a lot, but it won't murder them.

The Squirrel
HP, CR ¼ or so
Saves are around CR 3
AC, CR 5
Attack bonus, CR 4
Damage, CR ¼ish
Abiltity DC, CR 3

This guy will run circles around a level 1-2 party, and it's going to land a couple 1 damage bites before it goes down, but one hit will splat it.

The Raven
HP, CR ¼ish
Saves, CR 1
AC, CR 2
Attack bonus, CR 2
Damage, CR ¼ish

I'd say CR 2, maybe 1. It won't kill anyone when it hits, and it'll be a bit tricky to hit, but it goes down quick once you do.

Where did you get the Monster Stats by CR table?

Also I was planning on using the bear as a sort of boss monster against a party of 3 level 1s. A natural attack psychic warrior, a gunslinger, and a alchemist. Do you think it too tough?

Bestiary indexes have lots of stuff, including stats-by-CR.
