You should be fine with those offsets, if memory serves me:
18x10 offset range is 42 - 47mm, so 46mm is good.
18x8.5 offset of 50mm is good.
Do a search on this site to confirm, add the word spacer or offset and you will find quite a bit of information.
(edit)
Also I have bought from those folks awhile back on eBay, got a very sweet deal on a set of 18's that are still on the car for going on two years with no issues, first set they sent me had some cosmetic blemishes on them (not much) but I emailed them back with a photo and they shipped out replacements the next day even before I shipped the first set back.
So for what I paid and the customer service I received at the time I have no regrets.
