I scanned in one of my Everway character sheets and prepared three PDFs, at 300dpi (6.2MB), 150dpi (1.6MB) and 75dpi (412KB).
I also uploaded the 75dpi and 150dpi images to the Everway yahoo group that Brian mentioned. Unfortunately, at the time they had a file size limit of 5120KB, so I had to host the highest resolution sheet myself. Since then the file size limit has increased, so Longspeak was able to complete the set there too.
The scan of the original WOTC character sheet is reproduced without permission but is assumed to be allowed under fair use.
It sounds like you're asking which rolls gain the ubiquitous +1/2 level bonus. The easy answer is:
Most every d20 roll that gains an ability stat modifier as a bonus also gains 1/2 your level as a bonus to the roll.
- Attack rolls, initiative, skill checks, ability checks
Rolls that don't use a d20 don't get the level bonus.
d20 rolls that don't get an ability modifier as a bonus don't get the level bonus either.
All defenses also gain +1/2 level, so as to scale with attacks.
There are, of course, always edge cases, but the above is a good rule of thumb for 1/2 level bonuses.
Now, your other questions...
The "Check" box is for ability modifier + 1/2 level.
I personally find this produces more math than it's worth because then you have to subtract the level bonus when recalculating damage and the like, so I put just the ability mod in it.
"Misc." is for "Miscellaneous"
Extra bonus from feats, items, and so forth, go here.
"Add +1 to the modifier" means increase a +2 to a +3, and your attack increases by +1.
The +1 in their instruction is the +1/2 level bonus at level 2. If that counts as recalculation then yes, recalculate your attack.
Storm Hammer example
Attack: Wisdom vs. Fortitude
This means that you roll 1d20 + your Wisdom modifier + 1/2 your level + weapon proficiency (because Storm Hammer has the 'weapon' keyword) + any additional bonuses from weapon enhancement or feats or the like.
(When Wizards mentions an ability as part of a power or feature, like "Wisdom" in the attack line here, they mean the ability modifier. If they meant the whole stat, they'd have said "Wisdom score.")
If the result you get from the attack roll meets or breaks the target's Fortitude defense, you hit! So move to the hit line.
Hit: 1[W] + Wisdom modifier lightning and thunder damage.
Level 21: 2[W] + Wisdom modifier lightning and thunder damage.
That's 1[W] (the damage die your weapon deals, in your case 1d8) + your Wisdom modifier + any additional bonuses from weapon enhancement or feats or the like. The total of that roll is the damage you deal to the target of the attack.
The modifier you add to a roll only increases when one of those subcategories increases: If your Wisdom score increases, the modifier might also; or you could take a feat that gives you a bonus, or get a better weapon, and so forth. This means that your attack rolls will increase by at least 1 every other level (the +1/2 level bonus increases) even if you don't do anything else to bump them up. Your damage will probably increase more slowly, from feat and item drops, and as it says on the card at level 21 you get to roll two weapon dice instead of one.
Better Resources
All I can really point to is the Player's Handbook 1 or Heroes of the Fallen Lands. They'll walk you through this process and explain these mechanics much better than I can, in a scope far beyond what a question like this can cover. The Rules Compendium is also invaluable, but doesn't walk you through this process.

Each character sheet has a different layout - there is no standard, nor is there a required layout.
However, spells are not something available to all characters, so they are generally included on an entirely separate page.
