Your fighter looks nice, now you need gears. Who is selling you can see when you follow this link for example http://forums.d2jsp.org/forum.php?f=273
But first of all, when are ingame and in town, click on the market place and select items you looking for. Any advanced players ingame can help you on the first steps how to find items on marketplace.
You will need a few fgs for start gears, later more for better gears.
