6 and 8" Dobs are very comfortable to observe with while seated. I use stackable plastic stools, about $5 each from your local bargain shop. Use one seat near the horizon, stack two for normal viewing, maybe three at zenith if you're not too tall.
Re EPs, I'd grab a 32mm GSO Plossl for the maximum true field of view your scope is capable of, as well as a 15mm for deep sky and a 2x barlow, which will go well with the 15mm on planets.
Already mentioned: Planisphere, and I'd recommend Ellyard & Tirion's "Southern Sky Guide" - includes charts covering the entire sky and descriptions of the highlights for small scopes and binos. Great guide for starting out and beyond for a bargain price of around $25. (e.g. from Bintel)
Don't worry about the Moon "killing your eyes".
It won't! The Moon through the scope is not anywhere near as bright as many things in daylight, e.g., the blue sky on a sunny day. And in moderately good or better seeing you will see more detail without a filter. Filter is good idea for friends and family who might be seeing something so bright at night.
