Yes...absolutely you can. Just had this done last year with my AP2's. Don't know what is in your area but Golfsmith...Golf Galaxy or any pro shop can do it to your current irons. Hopefully you know your either upright or flat and how many degrees. This will make a world of difference with ball striking. Cost is about $5 per club...though it takes them 30 seconds for each club to bend.

Yes you can have the lie angle changed, if you know what the lie angle needs to be from your fitting go to a local pro shop and they should be able to bend them. I think AP1 can be bent up to 4 degrees either way. Just be sure you check that they are standard now, look up the AP1 specs and that way when they check them you will know if they have been adjusted before. Hope this helps, I went to a local fitter and they adjusted mine for me, I had to go -1* flat.
