Keeping a writing tablet close is a great tip. I have a nice little spiral bound notebook for taking notes. Some pages are just random notes, others have the math for my character's LRC suits on them. I even have a page of all the gardening maladies and their cures. =)
I also like to write little reference guides using the in-game books. I did this with the gardening, and it's a really quick way to find the right potion for an ailing plant. Fun too since mages usually like books, if you're into RP at all. =)
You can use the Spectral Spellbinders in New Haven for working on Resisting Spells. Everytime you try casting a spell, you can gain in Evaluating Intelligence, so keep on casting those spells!
You should be able to get LRC pieces easily...I was able to find many good pieces just laying around the bank in New Haven. Within a couple of weeks, I found some IDOC loot that was left behind, and sorted out enough pieces for *two* full suits! I've not got much else yet, but I'm thrilled to have these. You can read about IDOCs in the Homes and Castles Forum.
Remember to Insure your good LRC pieces right away...that way you won't lose them if you die. I lost some nice items while marking some runes. I recalled into an unknown location that ended up being a dangerous one! I had not bothered to insure my items as I thought I was only going to safe spots, hehe.
