I have accumulated a list of few answers for your questions....Any form of understanding will be appreciated
There is no arranging of your photo/photo albums but to make distinct albums you must put the photos in different folders and name of those folders will be your album name...say for example I have 5 awesome photos of my home and another 5 of my boss's villa,now if I want to keep them in different albums I make a folder named "big dude" and then put the boss's photos(villa) into "big dude" folder,then I create another named "awesome dude" and put my home photos into that folder. Now all I have to do is select the photos tab from iTunes when my iPad is connected to PC and select those folders to sync,now when perilous backup process is happening for all eternity and hopefully gets done before the judgement day, I just go to photos in my iPad,hit the album in the top bar and there we are Big Dude has villa and Awesome dude has awesome home photos.
I dont know how you are accessing your gmail but there is a trash bin image and the archive button,now if you want to delete the emails then hit the trash button,it's that simple. Now for the archive,it kind of keep away for forgetting later,when you archive an email,the email is removed from your inbox and goes to "All Emails" folder,so it won't be bugging you anymore but if you later need it then you can go to all emails folder and you can have it. Now if you are accessing the gmail from the Mails in iPad then yes there are no awesome "destroy 'em all" or trash icon,so what you do is select the message you want to remove, hit the "folder icon" with a down arrow in it,the first button from the left, beside the "box button" with a similar arrow in it, now you'll see all the folders in your gmail,as it says,just tap the "Trash" folder and there you are,that email will pain you no more,but make sure that the mail you selected is actually the one you wanted to remove/delete before hitting the folder icon.
Not charging means literally not charging,your USB as well as mine and many others' are of old age,so they can't provide enough power to charge,so the iPad gets power but can't charge. To charge the iPad connecting it to your PC,you must put it into the sleeping mode,that is hit the power button once and the screen will go black. But it is really not great as the charging takes longer and less effective.
For the dictionary you can add custom word by correcting a few times. Say for example I type iwhat but iPad started showing "what" in a white tab below the word,what i did was just hit the tab and completed typing iwhat,and from now on I will be hitting the white tab every time it appears for iwhat,and eventually iPad will get that iwhat is a new correct word and remember it bugging me no more with a correction. I am not sure how many hitting it requires but it does work. The best way is to complete the typing without bothering with the correction suggestion.
I don't know what form of folder you want to make,but if you want to keep all those irritating app icons from your home screen(iPad desktop) into a tidy little folder then you need ios4.2+,just hold onto any icon for a while to summon an iearthquake that will make the icons shake in their places,then drag one icon onto another and they will go into a folder. Then once everything is tidy enough and you are happy,just hit the home button(the tiny button on the iPad that closes the apps) to stop the iearthquake.P.S: oh yea!! you can summon an iearthquake in iPad,that felt good, but too bad you can't summon one in the real world.
I'm not sure about the pages app but it's supposed to be simple as saving the doc,and Pages will ask the name you want to save the document as.
Any Bluetooth keyboard will work with your iPad that can range from 10$ simple ones to 200USD multimedia ones with infinite number of buttons,but it must support Bluetooth 2.0 thingy which every keyboard does these days unless you find an ancient Bluetooth keyboard though. Make sure the buttons are soft enough and well spaced unless you want to get all sorts of wrist pains.
If you have any questions then feel free to ask and other awesome people here will help you as well once they get time.
Good luck.
