Imho, looks good for a level 39 forcewave warlord. If you want to look for gear (also check the vendors - some of the stuff I used at this level was not found but bought), try to get stuff which increases your casting speed - so mainly try to get a 2h weapon with casting speed and gloves with casting speed (with restless remains), than also invest in the respective skill (Squad Tactics), you should now also slowly reach areas where you can try to farm a Obsidian War Cleavers - get one. And try to farm a nice Mogara’s Fangs (from https://www.grimtools.com/map/markers/bosses/11289) to replace the amulett (as your amulett is not bad, you will likely need some tries to get a nice enough one - but with a bit of luck, you will get one with of Supremacy - investing here a bit of time imho does not harm as amuletts and rings will not become outdated that quickly - compared to other stuff). Just don’t overinvest in general in farming now, the gear you get now will become outdated rather soon (especially: weapons and armor) and you will need to get a higher level versions.
Regarding resistances - while I am surely on the lower end with my resistances (your character has much better resistances than my one had at this level), at this level it is imho not necessary to overinvest (means: making to much other comprises just to get all values up to 80), but it will become more important later. And like @tqFan wrote - having some alternatives in the stash, will make it later easier to adjust to found/bought gear options (just remember to sell the outdated (lower level) stuff from time to time).
And instead of Ectoplasm, I prefer Mark of Illusions for rings if I need more energy at this level - because of the other boni provides. Warlord has also the advantage that Presence of Virtue will help a lot with energy regen later.
