It is according to what your crank design is.
1st. design. This is a solid crank. Look at your crank. One side will have a nut, and a race with slots in it. If this is yours then you take off the pedal on the side of the nut. Now take off the nut, use a screwdriver to remove the race. Pull that bearing out, then push the crank through the opening, removing the other bearing. If you have a multiple speed bike you have to remove the sprockets first.
2nd design. After removing the sprockets there is a bolt holding the crank arms on the shaft that the bearing are on. Remove the cranks and then remove the bearings the same as above.

impossible to tell you without knowing the bike brand and model and year, although you have provided that 1999.
If you take into a bike shop, which is the usual place to purchase the parts you need, they will be able to tell you what size Bottom Bracket will fit your bike, also what options you will have for replacement cranks and bottom bracket. This could be a very complicated issue when replacing with parts that are 11-12 years newer, the shop will be best equipped to give you all your options.

Yes, once you remove the crank arms and the pedals, you will need a special tool to remove the bottom bracket that contains the sealed bearings.
Here is a set of nice quick YouTube videos on how to replace a bottom bracket which shows the tools and techniques required:

If you want to replace the bottom bracket yourself, just bring those details into your local bike shop and ask them for the correct tool and replacement bottom bracket to purchase. If you just wanted to have them do the work, I don't think they would charge you more than $30 labour for it, plus the cost of parts of course.
Anyway, please comment back here to this page if you have any questions, have difficulty accessing the links, or just require further general assistance and I will respond as soon as I see it.
Thank you very much and good luck.

No one makes manuals for specific models of ordinary bikes, especially Schwinn. Try their website for the generic manual.
As far as the BB goes, it hardly matters what it IS right now. You can and should replace it with a cartridge-style one to make adjustment a no-brainer. A bike shop should be consulted as there is a Black Art to matching up the old cranks to the new BB shaft so the chainline stays about the same. Special tools are also required but DIY is possible.
