You might want to post questions like this over on the Numbers community since it's more likely you'll find expertise there.
However, this one I can help with.  If not already showing, you need to turn on the Inspector in Numbers.  You do that by clicking on the Inspector icon in the upper right, showing the inspector box highlighted in red below:
Now select the cell(s) you want to format and click on the fourth tab (the one with the "42" in a box).  If want no currency sign, select number as your format, while if you want a currency symbol select currency as the format.
Next to the "Decimals" option is the box in which you can select your "negative" format--you have four options for showing negative numbers, two of which will place negative numbers in parenthesis.
Note that the inspector box controls a number of options and settings in Numbers. 
If you used to working with Excel you have to understand that Numbers works entirely differently and will have more than a bit of a learning curve. 
Generally I find Numbers is the weakest of the iWork offerings.  It is a useful program if you need a heaviliy formatted presentation of pure spreadsheet data, though if you want formatted spreadsheets in a mainly text report the Word/Excel combination works better.
The program also falls short in a number of areas vs. Excel if your spreadsheet needs go beyond the basic.  It certainly isn't the most efficent at dealing with a large spreadsheet (and, in fact, the fact the default templates all have only a few rows is a good hint that this might not be the product for that megasheet :-) ).
But if you just have basic spreadsheet needs it certainly can do the job.
