You are in a pretty good spot right now since you have JBB, Fungi Staff, Ceremonial Iksar Chestplate, GCD Earring, and you are working on Black Fur Boots. Honestly you can get to 60 with this. As you already mentioned, you can buy a fungi along the way and resell it at 60. You also need to save up for spells, so it isn't too necessary to upgrade your gear much more.
Here are some suggestions if/when you get a chance:
Legs - Around your level (wait until you can use JBB) you can do
https://wiki.project1999.com/Kromrif_Military_Leggings quest, which is fun and not too hard. I used those for a while on my Shaman.
Wrist - Same quest line as the legs roughly can also get you this
https://wiki.project1999.com/Coldain...ary_Wristguard . Since you are an Ogre you should be doubious to the giants if you havent been killing them. You could also do
https://wiki.project1999.com/Bracer_of_Hammerfal if you have skyshrine faction.
arms - Cheapest upgrade would be
https://wiki.project1999.com/Giant_Scalemail_Sleeves . Otherwise these are good:
https://wiki.project1999.com/Crystal_Chitin_Armplates or
https://wiki.project1999.com/Rune_Crafter%27s_Vambraces or
https://wiki.project1999.com/Gladiat..._Chain_Sleeves
Belt - If you keep up your giant faction you can do this quest at later levels, probably high 50s
https://wiki.project1999.com/Girdle_of_Reflection . Otherwise
https://wiki.project1999.com/Spider_Fur_Belt
Gloves -
https://wiki.project1999.com/Coldain_Skin_Gloves . You won't need haste once you get JBB.
Range -
https://wiki.project1999.com/Idol_of_the_Thorned . If you have skyshrine faction you can try your luck for
https://wiki.project1999.com/Talisman_of_Benevolence , but it can be a pain to get to west wastes over and over if you play this toon as a main.
