(Non WoW) Guild website with WordPress

Hey there, thinking of creating a non template like website for my Sw:Tor guild, I came upon WordPress, my question is simple, is this possible?

Features the guild site “must” have.
– Member signup ability and member list. I’d like to display the guild ranks on the site as well, maybe as an admin set rank feature? On the memberlist I would like to have some info etc of members as date joined date last seen, rank, etc etc.
– Calendar with response possibility. IE event on comming Saturday and I want to know of my members can attend or not. (Rather won’t have it just by commenting on a post but something with an easier overview.)
– Recruitment feature in a sitebar. Drew something up in Photoshop where I need to add text by typing (tested it as a HTML page, looked good, just want the page in the site bar at all pages).
– Progress tracker (same as above)
– Forums. Externally when it needs to but I’d love to have it match the looks of the wordpress site and that clicking between the wordpress site and forums is easier then switching back and forth in browser windows or tabs.
– Gallery with screenshots of progression kills, would love if not only admin could post if possible.

To be clear I’m not asking you guys to create my guildsite, got plenty of time and am eager enough to learn. Created a template with artisteer and the website is located at guild.brouba.nl (untill i actually knows it’s possible and I buy a domain and all.)

Please don’t let me go back to templatesites.

Naule.
