the first - theres a little dark butten beside nearly every "post function" on steam where you can find a few but usefull bb-codes to enhance readability ;-)
(named links would be nice)

the second - if you look at your modpage as autor you can see some options on the right side - one of them called "add/remove required items" ;-)
(wich may be an easyer option by so much mods - but pls dont use it when you only have to add 2-6 mods - quite anoying to click that stupid window away AFTER i read the description! xP)

both are quite obvious if you just spend some time on your creations like you did with you realy nice pictures! - sorry to put this into a spoiler but i cant understand why the hell so much people overlook BOTH OPTIONS so often -.-# ♥♥♥♥♥♥♥♥♥♥! :D *raging end*
(there must be a much religios people at valve if they censor "♥♥♥♥♥♥♥ed"="♥♥♥♥♥♥♥♥♥♥" :D)

i hope i coult help you :-)
