With TTF fonts, you need to use the SMOOTHFONT flag if you plan to scale it - not sure if that effects the original size though. TTFs are internally converted to bitmap fonts anyway.
With images, similar problem, but use FILTEREDIMAGE and/or MIPMAPPEDIMAGE flags when scaling.
If you have images that are too small from the outset, it'll look crap whatever you do.
[edit] This just in from Captain Obvious - don't forget to use ALPHABLEND when drawing fonts.
