Boss progression for a complete noob at pvm.

Hey there everyone! I wanted to get some opinions on what a good boss progression ladder would be for mechanics and gear for an ironman with next to no pvm experience? I can kill Sarachnis fairly well and already have racked up about 60 Sarach kills, but that is about the only boss apart from barrows that I can do confidently. Being an Ironman, BTW, I have no choice but to solo every boss, so any help would be greatly appreciated on devising a list of good starters for gear and experience! Thank you everyone for being an awesome community!
