I did get a new soldering iron with temperature control. It goes up to 480c or something and I found that around ~300 was good enough to quickly remove the solder from the existing port and removing it.
Only hard part was sucking the liquid solder up. I got one of those pumps that goes "PLUNK" (hehe) and it did not get all the solder off it really. I had to hold it at an angle as not to touch the soldering iron and if I removed the soldering iron and quickly placed the pump over it, the solder was already hard again.. Need more practice I guess, or, since this was such a tight spot, one of those suction bands instead of a pump.
Anyway, the ide port is all gone now and it looks clean and nice. If anyone else is planning the same thing, I can say that the IDE port on the motherboard was actually not one big 44port plate but 2x22 ports, so you can replace only half of it if you like =) Still waiting on the new one.
If this works, I'll probably ruin the motherboard, but if it works, I'll replace the caps as well. Couldn't you buy a whole set of those from somewhere? Thought I saw that somewhere but can not remember from where.
Edit: Found this one:

If I look at the first cap needed, would this one work? Its got a higher voltage but that should be OK, no? Been a while since i was in school.
