I don't have the book anymore so I can't look it up to be specific here, sorry.
Well, like Olaf says, the feats that are required to use the items are free with the ritual - albeit a ritual that requires some sort of in-character task, and a decent gold expenditure.
There are feats which allow you to improve usage of certain abilites (for example, spell like abilites can be empowered) but they are by no means obligatory to make such an item worthwhile. (that's perhaps a matter of opinion, of course - but I'm pretty sure the kind of spells that such items are packing are relevant enough at the appropriate levels.)
My game uses Weapons of Legacy a bit - one Half-Orc barbarian PC has a dragonbane Greataxe, the Dwarf Wizard has a Quarterstaff that's acquiring powers connected to astrology and time. They're at level 11 now, and just reaching the stage where further progress must be made to make the items next set of advances kick in - and the Half-Orc player in paticular in champing at the bit to get them.
Yes, the penalities are there, and some people might find them counterintuitive - why should a magical weapon that gives you pluses to hit also give you a negative to BAB? But then, my group were pretty cool with the "Stormbringer-style magical weapon which changes you" approach, and in both cases that I've used them it's been for ancient items where it's easy to imaginee them being a hindrance as well as a boon because of all the power invested in them. People who cannot see beyond the losses of HP or to hit are really missing the scale of these things, IMHO - like Heap says, it's not so much as to make a character incompetant in battle or anything. How big a deal is a lost 3rd level slot, or a -2 to all saves? You'll notice it, but considering you're somewhat ahead of the treasure curve now, it's a clear tradeoff.
Weapons Of Legacy is a pretty cool book, in my opinion. The exact rules are perhaps something for personal taste, and how bad the penalties and how strong the items can be flavoured to taste - if you're comfortable with the power level it will produce, chucking all the negativesand using the power scaling option is just as valid a way of doing things..
