Help needed for designing rules for concepts.

Well, to start off with, I need to work on the Reputation point system. The Reputation Point system is crucial for gaugeing the success of a member of the Etchers of the Mark, and the stat plays a role in most of the Sect Feats and PrCs I'm developing.
I basically need to give a bit of a variation of the Event-Based Reputation system as presented in Unearthed Arcana. If you don't have it, I'll boil it down for you.
After completeing an adventure a character generaly gets 0,1/2, or 1 RP. If the outcome of the adventure affected and got the attention of a city, he/she gets one point; if a smaller community, half a point; if very few/ no people, 0 points. (The book breaks down the random story-hook chart by RP award to show examples.) When encountering a new person, a bonus or penalty is given to the reaction roll/ social skill roll, depending on how the npc would view the character.
Thankfully this is pretty simple. Unfortunately, I need to muck this up a bit by adding additional ways to gain reputation, primarily performance and crafting/magic item creation.
My thoughts for performance were to keep track of total tips recieved for performance. Whenever this amount exceeds r^2*1000 gp + 1000 gp, where r is equal to the character's current RP score, the character gains 1/2 a Reputation Point.
If this were used for producers of goods however, an artisan's reputation would skyrocket.
Any ideas?

First off, I forgot to do so in my last post, but will rectify this now. Thank you all for taking time to work with me on this. When I finally get around to posting more of my work I will make sure to acknowledge those of you who help me with this. Now, onto some of your points.

Actually, that's part that I left out. In UA it give the example of someone from the Prime that is a new arrival in Sigil. Since no one in Sigil would have heard of the character, he does not gain the benefit of his Reputation. However, once he does something to gain at least 1/2 a Reputation Point, it argues, some people in Sigil would look into the character's background enabling him to get full use of his Reputation score. This goes for going to any new area. I was going to count any plane, demiplane, or Prime world as different areas, and even allow the DM to rule that even smaller divisions might count.

Well, aside from bonuses/penalties to reactions, I was going to make feats and PrC powers that give a Gloryhound a scaling amount of power directly related to his Reputation.

I recently uploaded my write up of the Sect to the site. As of the time of this post, it can still be seen in the "New Articles" side bar on the home page and the message boards. Otherwise it can be found in the Factions & Sects section of Planar Portals.

Rest assured, these are all things I've be working on. One thing I've been thinking of is a feat progression that allows a Gloryhound to choose an item that is particularly associated with him and allow it to count as a magic item while in his possesion, but give the character negative levels if the item is too far from him, or in anothers possesion. I was going to make this a progression so that after a few feats, it could become an incredibly powerful item. I was also going to make both level and reputation requirements for these feats.

I also intended to make a "trademark" feat that would allow adventurers/performers/crafters to personalize moves/abilities/styles/works so as to be more recognizable. Needless to say, I have no idea of how to give a game mechanic benefit for this.

And as for bards, I've got that covered. Bards factor heavily into the Sect as can be seen by its founder. I have also started work on my first prestige class which is for good alligned adventurers, and is based on the Warrior Poets of the viking age, with a secondary focus on inspiring others and spreading the fame of other heroes. It basically gives Bardic Knowledge, some of the Bardic Music powers, and bonus feats from the sect feat list, the fighter feat list, and a few miscellaneous feats.
