How do you mean? You can fold based on existing indent, which will
fold all lines having the same indent into a single displayed line,
where "line" means a newline-terminated string.
Or, if you have a fold, you can use the >> operator to increase the
indent of everything inside the fold.
Or perhaps you mean something different.

Word wrapping and folding are two completely unrelated topics.
Again, what do you mean by wrapping? Usually this means you have a
single long line which Vim displays on many lines by "wrapping" the
text which goes past the edge of the window. This is accomplished by
setting the 'wrap' option and probably 'linebreak' as well so that Vim
only wraps at word boundaries.
Unfortunately, using this wrap method, there is no way to
automatically start the next displayed line at the appropriate indent
level unless you modify the Vim executable. Since you say you're not a
programmer, this is probably an intimidating task.
There are a couple of partial solutions. The first would be to use the
'showbreak' option, which will add text to be displayed at the
beginning of each wrapped line. This text can be simply a number of
spaces, in effect creating an indent for wrapped lines. However,
'showbreak' affects every line in the same way, regardless of indent.
The next option would be to not use this "soft wrap" feature, but
instead us a "hard wrap" and insert real line breaks to wrap your
text. If you set 'formatoptions' to contain the 't' and 'a' flags, and
set 'textwidth' appropriately, Vim will automatically reformat each
paragraph as you type it so you don't need to worry about keeping this
up-to-date.

I understand the :mkview command will save manual folds, which
the :loadview command will restore. There is probably a plugin to do
this for you automatically.
If you fold using another method (e.g. indent, as mentioned above)
then you can either set up a command in your .vimrc to automatically
set this fold method for certain file types or file names. For
example,
autocmd BufRead *.txt set foldmethod=indent
Or, you could include a line such as the following at either the top
or bottom of every file you wish to do this for:
vim: foldmethod=indent
This is called a "modeline". By default, Vim scans the first and last
few lines in a file for lines in this format, and uses them to set
options on a per-file basis, overriding your built-in defaults
and .vimrc settings. Many *nix systems disable these globally, but you
could re-enable them in your .vimrc if you have this problem.
