Hi - welcome to VG. What cards you like will depend on your personal tastes really, so all I can do is tell you is what girls and cards have impressed me. A couple of my most recent favourites are Sarah and Dominno, but they have cards near the top of the list, and as you suggested I'll restrict my suggestions to cards that are not on the first page.
My all-time favourite VG girl is Aria Giovanni, and I can highly recommend all three of her cards (especially "Vampire *****" - a0481), as long as you don't mind a naturaly voluptuous woman with a relatively mature build. If your into very slim girls and are turned off by women with a bit more meat on their bones though, you should probably avoid Aria.
My favourite blonde on the site is Karina. Her shows are not particularly explicit, but she's very sexy, great fun and probably the best dancer overall on VG. Her best cards are "Latino Party" (a0079), Tango Fever (a0081), and "Heartfelt Words" (a0078), although her other three are well worth a look as well.
Another favourite of mine is Shabba, and particularly her "Pool Party" card (a0534). She is a fantastic acrobatic pole dancer (the only girl on VG I've seen stripping while hanging upside down from the pole), and she gives arguably the most interactive and fun performances of any girl on VG. She is a very beautiful woman, but doesn't have the conventional "model girl" look, which tends to put some people off and I think that is the main reason her cards are not higher rated.
If you want sheer sex appeal there are few cards better than Marta's "Cherry Bomb" (a0353) or Trisha's "Black Pearl" bar (a0520). Two gorgeous brunettes with striking blue eyes and very shapely bodies. Both are fantastic and very erotic performers.
Another girl I can highly recommend is Carmen Gemini, who was voted the favourite VG girl by VG forum users, in a series poles here towards the end of 2009 and beginning of this year. I think her best cards are "Pink Paradise" (a0324) and "Majestic View"(a0321).
Suzie Q is undoubtedly VG's queen of pole dance. She has won both the "Miss Pole Dance Australia" and "Miss Pole Dance World" titles in past years, and has been runner up to the legendary Felix Cane (the worlds greatest pole dancer) on a number of occasions. Suzie is without doubt the best acrobatic pole dancer on VG. She is a very beautiful and sexy girl and an entertaining performer. She does have a quite muscular body though, and isn't everyone's cup of tea. If you enjoy spectacular pole dancing and a fun show, I can recommend all of Suzie's cards, but if pushed I would say "Miss Pole Dance" (a0496), "Gold Level" (a0497) and "Wild Dance" (a0498) are her best.
VG's only two black girls to date - Krystel and Felina - are also well worth checking out. Krystel's last couple of releases "Coco Beach" (a0466) and "Tropical Summer" (a0464) are particularly good, and Felina's "Black Queen" (a0349) is also a favourite of mine.
Other girls you might want to check out include Denisa K - all 4 of her cards are fantastic; Ennie - my favourite by her is "Sex Instructor" (a0187); Lucky - my favourite is "Strike" (a0200); Jennifer Max - my favourite is "Black Moth" (a0537); Tarra White - my favourite is "Full Desire" (a0547).
Finally I have to mention Kayla, another great performer who is often overlooked because she doesn't have the typical "model girl" look. She is my favourite Asian girl here, and her movement and stripping are amongst the most fluid, skilful and sexy on VG. All 3 of her cards are well worth a look, but I think her best is "Pleasant Evening" (a0594).
Please also keep in mind that none of these older shows were filmed in the latest high definition VG format and the image quality isn't as good as in the latest shows.
Hope this helps.
