For some reason, I thought Solonir was going for the spellsword class. Probably just old age...
Anyhow, Sing 3 and Dance 3 for the bladesinger are fine. Rework your skill points how you want. Like you say, I think that's about the only effect there is for you.
Argent: The changes to the paladin mean that it now advances a bit differently from the holy warrior. However, I think the holy warrior will work fine as it is now, so I don't see the need to retool too much on Gideon. When you do finally get the mount ability, I'll give you the option of having it around all the time (3rd ed) or summoning it once a day (3.5 ed). I don't care either way.
GW: There's some changes to the druid class, which I imagine you saw coming. Animal Empathy is a class ability instead of a skill now, so go ahead and redistribute those points (remember that the class ability is now based on Diplomacy, which is a class skill for druids). You'll get some new abilities like the spontaneous casting. If you could, go ahead and note your class abilities (wild shape, trackless step, etc) on your sheet just so I'll remember them when they come into play. We'll use the new animal companion rules for Apropos- although dire hawk isn't listed specifically, I think he'd fit into the lower-tier "special companion" brackets. So his special abilities, etc will be calculated as if you were a 1st-level druid.
Block: Monks have a few extra options now. Some of their lower-level abilities are treated as bonus feats. You could, if you desired, swap Improved Grapple for Stunning Fist, and Combat Reflexes for Deflect Arrows. Or you could keep them the way they are. The way monk attacks work has been changed: you have a BAB of +3 normally, or +2/+2 when using Flurry of Blows (which has been combined with the unarmed attack advancement). Quarterstaves are monk weapons now, you can take one if you like.
I think the AC bonus has been toned down, I calculate that your armor class should now be 16. But you get ki strike much earlier now, and can hit creatures who would normally require magical weapons. I don't think there are any changes to your skills.
That's about it for updates- I have all three core books, and I'm still going through them. I haven't gotten to much of the combat stuff yet, I plan to do that next. Everyone please take care of the updates and let me know if there are any questions.
Would it simplify things for people to make a Rogue's Gallery thread, or is this one ok for the PC sheets?
