Bad draw for Israel. Peer should win out, even though she was run over by Rus once in Fed Cup, and of course we should beat Portugal with ease (god forbid if we don't), but I wish I could share your optimism regarding the ties vs GBR and the Netherlands.
Yes Glushko was very good last year, but she beat some top 200 players (Linette, Kremer, Kostova), and top 100 ones are a very different story for her. From memory I think she has one such win for her career (Groth in a 25K in Australia, not counting the recent Israeli ch. final vs Peer). If she could beat one of Keothavong or Krajicek it would be a pleasant surprise.
Peer/Glushko aren't that good a team and are not favored in those ties either.
The young Dutch team were very impressive last year and I think they will win the group over the Brits.
Groups A-B (with Hungary missing its top two players) are considerably weaker than C and D.
(honestly I didn't even know there is such a player...)
Good luck to you
P.S. I wasn't aware that not too long ago you've fallen as low as Group III
